--Master Cylinders.



INTRODUCTION:

Okay, here goes:

The older I get, the more important stopping quickly becomes to me. In some ways, it becomes even more important than accelerating quickly. Without a cage to protect you, and out there with all the chattering folks in their 2-ton cars and SUV's and trucks, safety quickly becomes the #1 issue when riding around in the real world---and nothing means "safety" as much as a great set of brakes. So do yourself a favor, and make sure your braking system is all that it can be.......

http://www.xjbikes.com/forums/threads/two-things-that-will-keep-you-alive.113686/


First and foremost, make sure that your stock, original brake system is up to par. Make sure that:

* pads and shoes are within factory specs, and replace if necessary.
* the master cylinder(s) are working properly, and that the fluid is clean and flows freely, without any air bubbles. MAKE SURE THE TINY, MINUSCULE PRESSURE RELIEF PORT IN THE MASTER CYLINDER IS FREE AND CLEAR OR YOUR BRAKES WILL NEVER FULLY RELEASE AND WILL NOT ONLY WEAR QUICKER, BUT THE EXTRA HEAT BUILD-UP WILL:

* warp your rotors.
* wear out your pads.
* dramatically increase your stopping distance.

Brakes work by turning motion into heat, so if your brakes are already heated (due to constant engagement), well........you can guess the rest!

Continuing, please inspect and make sure that:

* the brake hoses are in great condition.
* the calipers are functioning properly, and not stuck or leaking.



* brake rotors are true, within specs as to thickness and runout, and do not exhibit any cracks around the mounting holes nor the outside edges, IF THEY HAVE CRACKS THEY NEED TO BE REPLACED!

To upgrade your brakes, consider:

* if you don't have dual front discs (all North American XJ550 and XJ650 Maxim and Midnight Maxim models), consider doing a conversion to such a set-up.
* install a big-bore master cylinder (as came standard on dual-disc bikes).
* replace stock rubber hoses with stainless-steel braided hoses. This will make a difference you can really feel!
* use higher-friction brake pads and shoes, such as sintered metallic materials. These work better than organic pads once they warm up, but do so at the cost of greatly reducing the life of your rotors and brake drum.




FRONT MASTER CYLINDERS:

mc1) OEM and aftermarket complete front and rear MASTER CYLINDERS, brand new units perfectly replace the originals. Contains lid, diaphram, piston assembly, and lead wires for fluid level switch (on models so equipped). Some master cylinders may NOT include the brake light switch, lever, or mounting hardware........please review the individual applications below for complete information. Lettering and information on the reservoir cover will differ in appearance from your original.

By the way, if you are considering upgrading from one size master cylinder (piston bore diameter) to another, here's the decision parameters that you'll want to consider:

NOTE: a few clarifications about use of the original XJ650 Maxim master cylinders versus the aftermarket cylinders.

There are a couple of differences you need to be aware of:

a) because the stock OEM master cylinder is designed to be used on the stock curvy "buckhorn" style handlebars, the stock master cylinder reservoir is oriented at a "tilted" (from horizontal) mounting angle. This "tilting" allows the mirror to be properly aligned for the use with the stock buckhorn bars and keeps the reservoir in a relatively level position.

b) the aftermarket master cylinder HCP3063WO is designed to mounted on "flat" (or, at least, "flatter") style handlebars, such as the ones found originally on all XJ-series bikes (except the XJ650 Maxim/Midnight Maxim, XJ750 Maxim/Midnight Maxim, or the XJ1100 models.....all of these models used tilted or curvy “buckhorn” style bars). All other models use fairly flat handlebars, and thus the replacement master cylinder will work on those bikes correctly; they leave the mirror mounted in the proper orientation.

c) thus the aftermarket HCP3063WO master cylinder is going to leave the stock mirror tilted at a rather crazy and semi-useless angle when installed on any model that had those curvy, "buckhorn" style bars, and we do not have a stock-style mirror substitute that "solves" this problem. About the only solution we offer is to use the "bar-end" style mirrors, which attach the mirrors to a mounting stem that fits inside the end of the handlebars (which requires modification of the grips by cutting away the rubber on the ends of them, but that is easy enough to do). Of course bar-end mirrors are kind of a unique looks, usually reserved for café- and bobber/rat- themed projects, and may look out of place on a stock “cruiser” style bike.

d) Also, on the XJ650 Maxim and Midnight Maxim models, the fluid outlet port (where the brake hose attaches), is facing "inward", towards the centerline of the bike (when the forks are pointed straight forward). The replacement HCP3063WO master cylinders have their fluid outlet port facing straight forward, and therefore your stock brake line has to be contorted to a rather odd angle to make it reach and fit this forward-facing outlet port. We do have available modified rubber or braided stainless steel brake lines for use of the aftermarket master cylinders on these bikes; their end fitting is rotated by the 90-degrees and extended by an appropriate length to allow it to attach to the aftermarket master cylinders properly.



HCP6277 OEM complete MASTER CYLINDER ASSEMBLY, brand new unit perfectly replaces your original. Comes with cover, diaphram, and piston assembly, ready to install. Hand lever, brake light switch, and mounting hardware is not included. Fits all XJ650 Turbo, XJ750P (24L), and XJ750P (37H) models. 16mm piston bore, horizontally level reservoir orientation, forward-facing fluid outlet port.

HCP3015 OEM complete MASTER CYLINDER ASSEMBLY, brand new unit perfectly replaces your original. Comes with cover, diaphragm, handlebar mounting clamp (but not the bolts), and piston assembly, ready to install. Hand lever, brake light switch, and handlebar clamp mounting bolts are not included. Fits all XJ550 non-North American models, 1982 XJ650RJ or RJC Seca models, all non-North American XJ650 models, all XJ700 and XJ750-X models, 1984 XJ750RL, all XJ900RK Seca models, and all XJ900RL models. 16mm piston bore, horizontally level reservoir orientation, forward-facing fluid outlet port.
$ 459.95



HCP24560 OEM complete MASTER CYLINDER ASSEMBLY, brand new unit perfectly replaces your original. Comes with cover, diaphram, and piston assembly, ready to install. Hand lever, brake light switch, and mounting bracket and hardware are not included, but are available separately. Fits all 1982 XJ750 Maxim and models. This unit has the low brake fluid sensor provision inside the reservoir as used on the 1982 models only. Sensor is not included. Reservoir cover is the later style and does not have the raised, polished “YAMAHA” wording as original. 16mm piston bore, horizontally tilted down reservoir orientation, towards-the-bike-centerline fluid outlet port. NOTE: the HCP1808WO aftermarket master cylinders can be used in place of the original master cylinder on these models, but because those are "level" orientation master cylinders, they will place the mirror mounting boss in a different position (and odd angle) compared to the original master cylinders.
$ 599.95

HCP3018 OEM complete MASTER CYLINDER ASSEMBLY, brand new unit perfectly replaces your original. Comes with cover, diaphram, and piston assembly, ready to install. Hand lever, brake light switch, and mounting bracket and hardware are not included, but are available separately. Fits all 1983 XJ750 Maxim and Midnight Maxim models. NOTE: this unit is identical to, and will also fit and work on the 1982 XJ750 Maxim, but it does not have the low brake fluid sensor inside the reservoir, and thus you will lose that function if this master cylinder is used on a 1982 model. You can bypass the sensor using our HCP19573 adapter wire below, which will prevent the dash "warning" from alarming constantly to warm you about a low brake fluid situation. Reservoir cover is the later style and does not have the raised, polished “YAMAHA” wording as original. 16mm piston bore, horizontally tilted down reservoir orientation, towards-the-bike-centerline fluid outlet port. Comes with a glass fluid level sight glass already installed! NOTE: the HCP1808WO aftermarket master cylinders can be used in place of the original master cylinder on these models, but because those are "level" orientation master cylinders, they will place the mirror mounting boss in a different position (and odd angle) compared to the original master cylinders.
$ 499.95


HCP19573 Aftermarket ADAPTER WIRE for low-brake fluid sensor bypass. Since the 1983 master cylinder has no provision for the low-fluid sensor, you need to by-pass the sensor so that the computer is fooled into thinking there is plenty of fluid in the reservoir.

e) If you want to retain the original low brake fluid warning feature, the only way to do this is to rebuild your original master cylinder, or, to obtain a correct used master cylinder (off of another 1982 XJ750 Maxim model) and rebuild it. Let us know if you are interested in this option and we can provide a full list of recommended rebuild parts.




Aftermarket Front Master Cylinders:

HCP3063WO Aftermarket complete MASTER CYLINDER ASSEMBLY, brand new aftermarket unit perfectly replaces your original. Comes with cover, diaphram, piston assembly, hand lever, mounting hardware, union bolt, and crush washer----completely ready to install. Fits all North American XJ550 models, although the hand lever that comes with this master cylinder will not have the same bend orientation as original. 13mm piston bore, horizontally level reservoir orientation, forward-facing fluid outlet port. NOTE: this aftermarket master cylinder can also be used in place of the original master cylinder on XJ650 Maxim and Midnight Maxim models, as well as all XJ1100 models, but because those are "level" orientation master cylinders, they will place the mirror mounting boss in a different position (and odd angle) compared to the original master cylinders on those models. NOTE: brake light switch is not included with this master cylinder and the proper switch should be ordered separately if needed NOTE: the HCP2667 clutch hand lever is the closest available match in style and finish to the hand lever that comes with this master cylinder. NOTE: this master cylinder has the proper left-hand threads for the stock Yamaha mirrors. This means that any other brand---Kawasaki, Honda, Suzuki, etc.---mirrors will not fit it, since all models besides Yamaha used standard right-hand threads for both the left and right side mirrors). Only Yamaha used left-hand threads on the right side mirror. If you wish to use your stock (or other) Yamaha mirrors with this master cylinder, you can use our mirror adaptors listed below.

Mirror Thread Adaptors:

Yamaha was unique in using left-hand (reverse) threads for the right side mirror........this allows the right-side mirror to "rotate loose" in case you hit something with it, rather than snapping the mirror stem (or master cylinder). Although this is a great and clever idea, it causes difficulties when using aftermarket or non-stock master cylinders, as they will not have the proper thread orientation needed to install the stock mirror. Our MIRROR ADAPTORS will allow you to use the stock Yamaha right side mirror on aftermarket master cylinders which have standard right-hand threads in the mirror mount bore.

HCP13236 Aftermarket set of MIRROR THREAD CONVERTERS, allows the use of any right-hand threaded, right side mirror on any stock Yamaha master cylinder that has the reverse left-hand threads for the mirror mounting. This adapter simply screws into the left-hand threaded hole in the master cylinder, and it has male right-hand threads in its upper receiver where a non-Yamaha mirror can mount into. These units will raise the height of the mirror by approximately 5/8" above the original mirror mounting point (on the master cylinder), Matched set does both the left and right side mirrors. These adaptors feature a low-gloss black finish.

Brake Hand Lever Cover or Boot:

hl11) Original flexible rubber accordion brake hand lever BOOT protects the hinge mechanism and switch from excess moisture and dirt. Note that XJ700 and XJ750-X models do not use a hand lever boot, but if you want to equip either of those models with a boot, then use either the HCP608 or HCP16520 versions listed below. Note that due to the extra-large "ball" end of the hand lever on the XJ700 and XJ750-X models, you will need to generously lubricate (dish soap, silicone, etc.) the rubber boot opening so that it can slide over the knob without tearing/splitting.

The HCP3063WO and the HCP1808WO master cylinders above come with the brake hand lever, but do not come with the protective boot, which you may want to add:


HCP608 OEM black accordion-pleated BRAKE HAND LEVER BOOT, correct fit and appearance as original.

FRONT MASTER CYLINDER REBUILD PARTS:

mc41) OEM and aftermarket brake MASTER CYLINDER REBUILD KITS contain all the operational parts you need to correctly rebuild your master cylinder: piston, piston seal, piston spring, piston rubber sealing boot, and retaining circlip. NOTE: the piston seal does not come pre-installed onto the piston, and at first glance, you may wonder "how the heck do you get that small seal opening over that large piston?". Well, lots of lube (brake fluid) and patience and a small, dull pry tool works wonders. Make sure that you install the seal with the flared seal "lip" facing towards the fluid outlet!

Yamaha actually specifies that your master cylinder should be rebuilt every 2 years.

Master cylinder rebuild kits contain the piston, the piston seal, the spring, the plunger end seal, the plunger dust boot and its retaining circlip.


A pictorial overview of the master cylinder rebuild process can be observed at:

NOTE1: be sure you very carefully clean and inspect your used, original master cylinder for any damage and verify that it can be rebuilt. If the pressed-in steel piston bore is badly scarred or pitted-rusted, then it must be honed to a silky-smooth finish before installing new components. If pits or scratches are too deep to be removed, it is best to obtain a replacement master cylinder (new or used) rather than to try to rebuild a damaged original. Remember, your life literally depends on your brakes....not always in day-to-day riding, but when it counts the most, in an emergency situation; and those always happen in the blink of an eye, and without prior warning.....


NOTE2: All original Yamaha front master cylinders have an extremely tiny "blow back" hole (actually a pressure release return passage) in the center of the bottom of the reservoir floor that must be clear and un-blocked in order for your master cylinder to function properly----if this hole is plugged, it will prevent the calipers from fully releasing when the brakes are NOT being applied, causing the brakes to always be slightly engaged. Brake system "dragging" will result, as well as brake rotor over-heating and warpage after a period of time.

This tiny hole is located within an area that is best described as what appears to be the beginning of a drilled hole that was "never completely drilled through" (this will make sense when you actually view the floor of the reservoir). In the very center of such area is this pressure release passage, and it takes about 1-2 un-stranded strands of wire to poke through this hole and remove any debris or gunk. This hole is not the much larger reservoir-to-piston chamber fluid transfer hole, which is huge compared to this pressure-relief passage. The pressure relief passage hole is normally just to the "side" or "behind" the larger (1mm diameter) fluid transfer hole, and "in line" with the centerline of the piston chamber, but "behind" the fluid transfer hole, towards the brake hand lever side of the master cylinder.

When rebuilding your master cylinder, make sure that this tiny relief passage is free and clear! Failure to clean this passage fully is one of the major over-looked "gotch-ya!" situations that arise when rebuilding your master cylinder.


A good picture of this relief port on the conventional (handlebar-mounted) master cylinders can be seen at:

You will also find your life being made a lot easier with the use of these special deep-reach circlip pliers, need to extract (and install) the interal circlip that holds the entire guts in the master cylinder:

bp1) Master Cylinder DEEP-REACH CIRCLIP PLIERS----these special extra-deep 90-degree angled circlip pliers allow you to easily remove and install the circlip (or "c'-clip) that hides way down inside the top of the plunger bore (below the rubber boot). Without a DEEP set of circlip pliers, you're going to fight and struggle with this part of your master cylinder rebuild project. Regular store-bought circlip pliers may have a 90-degree attachment, but unless they are extra-deep like these, they still won't be able to reach that circlip.

HCP1597 Aftermarket master cylinder CIRCLIP PLIERS, each:
$ 29.95

These and other special tools can be found in the BRAKE TOOLS SECTION of the catalog at the very end of this brake parts section.


You can check the condition of your master cylinder by disconnecting the brake hose at the master cylinder and performing a bench test by plugging off the fluid exit port and operating the hand lever to see if it will build pressure. If it does, then the master cylinder seals are in good condition. If, however, the master cylinder spurts fluid back up through the pressure-relief port, then a rebuild is definitely in order! NOTE: it is proper and correct for brake fluid to squirt up through this pressure relief hole only when the piston is retracting (hand lever released), as this is how the master cylinder relieves excess pressure from the brake calipers so the pads back off the rotors. But if the relief passage is plugged, your brakes will drag.

Of course, once you rebuild the master cylinder, you should perform the bench-test procedure once again, to make sure you have rebuilt it correctly. In either situation, you should bleed your brakes (and perhaps flush all of the old fluid) whenever the brake system has been opened, as well as replacing the crush washers at the master cylinder union bolt.

NOTE: if your master cylinder fails to build pressure after a rebuild, you may have installed the rubber piston seals or the plunger spring incorrectly (backwards).



Frequently, the question comes up as to how the various component bits and pieces of the replacement master cylinder kits should be installed.....as the fluid plunger (piston) can be installed in two different orientations within the bore, and the rubber fluid seals can also be oriented in two different directions. In order for your master cylinder to operate properly, it is vital that you get all of these orientations correct!

Also, please be aware that the factory diagrams and illustrations in both the factory service manuals and in the aftermarket service manuals illustrate the original factory piston and components, and thus tend to appear to be "wrong" in comparison to the contents of the currently available rebuild components.....actually, the illustrations are correct, but aftermarket master cylinder rebuild kits do away with the separate rubber spring "cup seal" that is illustrated in the original factory diagrams. Instead, the aftermarket kits place the forward fluid pressure seal onto the piston itself (rather than resting at the end of piston), and this combined "forward pressure seal and spring cup" is thus eliminated in the replacement rebuild kits-----the spring fits over the end "snout" of the piston unit, rather than into the original rubber "cup" seal.

The factory drawings can lead one to believe that the plunger/piston is originally of a 2-piece design; this is not correct, they are always a 1-piece design and the original separate forward pressure seal/spring "cup" makes the drawings appear as if the not fully or correctly illustrated piston is actually two pieces!


Here's how it really works: by the way, it is very helpful if you carefully note or mark the original piston as it is extracted out of the master cylinder bore, in order to eliminate confusion later.

The replacement piston has three seal location "lands" where a seal fits ("lands") onto the piston. Two of these lands are for the fluid pressure seals....one on each end of the three spiraling "corkscrew" fluid reliefs....while the one land near the "fat" end of the piston is where the large rubber weather-tight boot is placed.

Please note carefully that the two fluid pressure seals have different size internal diameter openings, and thus fit onto their corresponding smaller and larger diameter seal lands at each end of the "corkscrew". These seals fit with their open face or "lips" facing towards the fluid output port of the master cylinder.

The tapered return spring has different sized ends; the smaller end fits over the small "stud" or "snout" of the piston. The larger end of the spring will thus be the first object that "enters" the master cylinder bore as you re-assemble the piston into the master cylinder bore.

Please note right here that the drawings in the factory service manual do not illustrate this small "snout" on the piston end (where the small end of the return springs fits over), and thus the entire diagram can lead you to believe that this small "snout" actually fits toward the hand lever, which is incorrect!

If you ever get confused as to which end of the piston is which, look at your original piston, and note which end face has scars and (probably) metal displacement from it very end face..........the one that shows the metal displacement is the one that the hand lever was operating upon!

The large rubber "boot" fits into the ring land that is near the lever-end of the piston, and it fits "down" towards the length of the piston, not "outwards". You will note that the large open end of this boot actually has a stiff metal ring embedded within it.

This rubber boot will be the last thing that is installed, after the piston unit has been installed into the master cylinder bore, the piston depressed, and the retaining circlip installed. Only then can the rubber boot be installed onto the end of the piston.



Assembly Notes:

- make sure that the internal master cylinder bore is completely clean, smooth, and free of nicks, junk, gunk, and old fluid or rubber remnants.

- lubricate the master cylinder bore and the entire piston assembly with clean brake fluid before trying to install the piston into the master cylinder bore.

- make sure that the seal lips do not "turn inside out" or "roll back" on themselves as the plunger is inserted into the m/c............a "rotating" motion of the plunger as it is being inserted can be useful in preventing such as occurrence.

- the wide end of the spring goes toward the fluid outlet port.

- the piston rubber pressure rings that goes around the plunger have an open face with a lip on it....and that lip should be oriented "in" towards the fluid outlet port.

- the metal circlip that retains the plunger in the cylinder bore goes on before the outer plunger dust boot is installed.

If you are re-using the original master cylinder components, then:

- the open end of the hat-shaped rubber cup goes over the narrow end of the spring.........and that lip should be oriented "in" towards the fluid outlet port.

Front Master Cylinder Rebuild Kits:

These OEM and aftermarket kits contain the correct parts needed to rebuild your original master cylinder. Most kits are available in either a basic of full version as described below:

SEALS AND SPRING KITS contain the piston seals, return spring, piston boot, piston retainer clip, and a pair of union bolt crush washers. Since these kits contain all of the main “wear parts”, it’s now affordable to actually follow Yamaha’s suggested rebuild interval (every 2 years) without “braking” (pun intended!) the bank! Other parts needed to properly rebuild an original master cylinder --- the piston, the fluid level sight window, cover, cover diaphragm, cover screws or nuts, mounting clamps, fluid level sensor hardware (when used), etc. are not included.

BASIC REBUILD KITS contain the typical main working “guts” of your master cylinder: the aluminum piston, its seals, return spring, spring cup (when used), piston boot, and its retainer clip. Other parts needed to properly rebuild an original master cylinder --- the fluid level sight window, cover, cover diaphragm, cover screws or nuts, mounting clamps, fluid level sensor hardware (when used), etc. are not included.

FULL REBUILD KITS contain all of the items in the basic rebuild kit, plus a fluid return hole clean-out wire, the replacement fluid level glass sight window (on models which use them), adhesive for the glass window, a packet of assembly grease, the reservoir cover diaphragm, the cover screws, and ---- models requiring them ---- the fluid level sensor hardware and sealing o-ring.

NOTE: before ordering your master cylinder rebuild parts, please take a moment to inspect and confirm that your bike does indeed have a factory original (for your model) master cylinder on it. After all these years….and so many previous owners…...there’s no telling what’s resting up there on your handlebars, and since rebuild parts are quite specific designed to work only with a particular style master cylinder ----- well, it’s best to be safe than sorry!

So here are the clues for original master cylinder identification:

XJ550 all North American models: the cylinder body will have the size 1/2 and the word NISSIN cast into it along the larger rear facing side of the cylinder body. Original (1981-83) cylinders will have the word NISSIN in all capital, block-style letters, while later “replacement” cylinders will have the word NISSIN appear as a stylized semi-script, with the two “s” letters layered on top of each other. Both types will accept all of the parts that we have listed below as fitting original master cylinders.

XJ550 non-North American models (dual-disc bikes): the cylinder body will have the word NISSIN cast into it along the larger rear facing side of the cylinder body, and have the size 5/8 cast into the forward face of the cylinder body just to the left of the fluid outlet port (where the brake line attaches).

1984-85 FJ600 and all XJ900 F, N, and FN models: the cylinder body will have the size 5/8 cast into large front face side of the cylinder body just above the fluid outlet port (where the brake line attaches), and the manufacturer name does not appear anywhere on the cylinder body.

XJ600 Seca II models: the cylinder body will have the size 14 (meaning a 14mm bore) cast into large front face side of the cylinder body, and the manufacturer name does not appear anywhere on the cylinder body.

XJ650 Maxim and Midnight Maxim North American models (single-disc): the cylinder body will have the size 14 (meaning a 14mm bore) and the word NISSIN cast into it along the rear face of the piston bore. Also note that these cylinder bodies have a "tilted orientation" to compensate for their "angled" handlebars.

XJ650 non-North American (dual disc) models, XJ650RJ Seca, all XJ700, XJ750-X, XJ750RL, and XJ900RK and RL models: the cylinder body will have the word NISSIN cast into it along the larger rear facing side of the cylinder body, and have the size 5/8 cast into the forward face of the cylinder body just to the left of the fluid outlet port (where the brake line attaches).

XJ650 Turbo, 1982-83 XJ750 Maxim and Midnight Maxim, and all XJ750 Police models: the master cylinder body will have the size 5/8 cast into it along the larger rear facing side of the cylinder body, and the word NISSIN does not appear anywhere on the cylinder body. The XJ650 Turbo, 1982 XJ750 Maxim, and XJ750P master cylinders have a small (1/4” diameter) hole in the base of the reservoir where the fluid level sensor wires exit the inside of the reservoir. Also note that both the 1982 and 1983 XJ750 Maxim/Midnight Maxim model cylinder bodies have a "tilted orientation" to compensate for their "angled" handlebars.

XJ750 Seca and all XJ750 Euro models: the long skinny cylinder body will have the size 11/16 (meaning a 17.5mm bore) cast into it along on side the piston bore, and the word NISSIN does not appear anywhere on the cylinder body.

XJ1100 Maxim and Midnight Maxim models: the cylinder body will have the size 14 (meaning a 14mm bore) cast into it along the rear face of the piston bore, and the word NISSIN does not appear anywhere on the cylinder body. The bottom of the reservoir has a small (1/4” diameter) hole in where the fluid level sensor wires exit the inside of the reservoir. Also note that these cylinder bodies have a "tilted orientation" to compensate for their "angled" handlebars.

NOTE: XJ750 Police (24L, 33V, and 39Y models) used the XJ650 Turbo master cylinder with XJ750 Seca calipers and rotors, and XJ650 Turbo style forks without anti-dive.

NOTE: XJ750 Police (37H models) used the XJ650 Turbo master cylinder with XJ650 Turbo/XJ750 Maxim/Midnight Maxim calipers, XJ650 Turbo rotors, and XJ900 style forks with anti-dive.


If your master cylinder does not match the above descriptions, then we may not be able to assist you with rebuild parts for it…..there are an incredible number of both original and aftermarket master cylinders that were/are available, they all look somewhat the same, and they all may or may not accept nor function properly (or at all!) with component intended for use with the original master cylinder used on your bike!


NOTE: many times you may end up needing the flexible rubber PLUNGER BOOT that sits on the end (outside of the piston bore), a it is very easy to rip this boot during installation or service (this is the boot that is held in place by the external circlip listed below). This boot is included in all of the following master cylinder rebuild kits, but it is also available separate if just that boot is needed:

$ 11.95


NOTE: at times you may also end up needing just the CIRCLIP that retains the piston in its bore (the HCP21232 boot above fits over/on top of this circlip). This circlip is included in all of the following master cylinder rebuild kits, but it is also available separate if only it is needed:

FRONT MASTER CYLINDER RESERVOIR COVER SCREWS:

mc16) Master Cylinder Reservoir COVER SCREWS: they're always buggered up, and there's never a better time to replace these than now! Offered in a variety of both stock (phillips-drive) and hex-drive configurations, in both plain and stainless steel.

NOTE: Original reservoir cover screws on all models were always black plated. If you wish to retain the original appearance of the screws that we offer that are zinc- or bright-plated, a quick little spray of black paint will fix that.....

HINT: seized or destroyed cover screws can be drilled out using a 5/32nd or 3/16th inch drill bit to carefully drill the head out, and then the cover can be removed, leaving a short part of the threaded shaft of the screw to grab onto with vise grips, etc. for final removal. A good quality 1/4" left-hand (reverse-grab) drill bit can sometimes be successfully used to release stuck fastener screws.

If the screw holes need their threads cleaned or re-tapped, this is what you'll need:

HCP2396 THREAD CHASER AND CLEAN-UP TAP, made from a high-speed titanium nitride coated steel. For use on all XJ-series (except XJ750 Seca and XJ750 Euro models with cable-operated master cylinder) and 1981 XS1100 Midnight Special front master cylinder cover hold-down screws.
$ 12.95

HCP2397 THREAD CHASER AND CLEAN-UP TAP, made from a high-speed titanium nitride coated steel. For use on all XS1100 front master cylinder cover hold-down screws (except 1981 XS1100 Midnight Special models).
$ 12.95


HCP28170 Aftermarket thread tap or EZ-out extractor TAP HANDLE, featuring offset tap handles and fully adjustable head for all m3-m12 size taps and size 0 to ½” extractors. This is the proper way to hold a tap or extractor to insure that the force is directed straight down and doesn’t “wobble” as you are cutting, reaming, or extracting. Much better than using pliers or vise-grips to hold the tool……..
$ 17.95



The following screws fit all of these models: 1981-82 XJ550 all models, all XJ650 (except Turbo) models, 1982 XJ750 Maxims, XJ1100 (front) and XS1100LH (front) models.

NOTE: some 1981-2 XJ550 models may also use these longer screws as specified only for the 1983 XJ550 models. You may wish to measure the overall height of your original screws before ordering. The 1981-2 screws are a total height of 10mm, while the 1983 screws are 12mm in total height. While it is acceptable to use the shorter screw in place of the longer ones, it is not possible to use the longer screws in place of the shorter ones.

MASTER CYLINDER FLUID SIGHT WINDOW:

mc2) ) While you're rebuilding or even replacing your front master cylinder, you might as well go ahead and replace that dull, clouded, cracked thick plastic sight "window" that, once upon a time, allowed you to see the level of brake fluid in the reservoir. The original "transparent" round plastic window ages neither gracefully nor well over time, and becomes cloudy within a few years. Our replacement windows are available either as an original-style replacement plastic window (complete with rear metal “anti-splash” disc), or for a longer lasting, clearer view, as a flat mineral glass window that is the correct size (and unlike the plastic windows, the glass windows won't ever get cloudy). Both are one of those small details that you can step back, look at, and say to yourself: "Kewl".

Okay, all that's the good news. The bad news is that the old plastic window and --- in the case of the replacement plastic windows, the metal ring --- can be a beast to remove. Sometimes, they come out all nice and easy. Sometimes, you have to do battle, and as that classic old Pink Floyd song suggests: "One of these days, I'm going to cut you into little pieces......". You get the idea. You'll have to fight, struggle, and then win.

The replacement plastic windows will all show a small amount of “haze” and/or surface “scratches” due to the manufacturing process, and, like the original plastic windows, will again cloud up over time; while the replacement glass windows require a little more effort to install, the result is a much higher quality and longer-lasting appearance. Replacement glass windows come with illustrated install instructions.

Our HCP15662 radial disc brush will make the cleaning and polishing of the "seat" area (where the new sight window will be installed) a simple task for the installation or either type window.

Here is a good video showing the basic (generic) installation of a sight window:

www.youtube.com/watch?v=F_yo3FnH6DM



Replacement Plastic Fluid Level Windows:

These windows will only fit the later “Style A” original front master cylinder reservoirs, but we’ve found that on some original master cylinders, the bore hole in the reservoir body (where the sight window is fitted), may not be quite dimensionally correct…..which is why the metal “trim ring” or fitting ring was used, to take up any very minor differences in order to insure a tight, leak-proof fit. Since you will need to remove this fitting ring in order to install these plastic windows……..they come with a bonded fitting ring already installed onto the plastic window…..you should be aware that the removal process can be a challenge, and, you may need to clean and/or perform a minor re-sizing of the bore opening to get a fit of the replacement window into the cavity. Most times, we can heat up the m/c reservoir gently with a heat gun, etc. which expands the bore cavity just enough to make installation of the new window easy enough (but, don’t be surprised if you still need to “drive” the sight window in, using a piece of wood against the face of the window and gently hammering it on home………).

These plastic windows are a lower-cost option than our flat glass windows, but they too will eventually cloud over (5+ years) like the originals did.

Here’s the difference between an “A” and “B” style original master cylinder (and their sight windows)::

http://www.xj4ever.com/choosing a sight glass.pdf


HCP27626 Aftermarket front brake master cylinder glass brake fluid level SIGHT WINDOW, correct size and thickness plastic window with bonded outer metal “fitting band” and rear anti-splash disc……just like original. NOTE: fits all Style A front master cylinders, and all XJ1100 and 1981 XS1100LH Midnight Special rear master cylinder fluid reservoirs. Requires the removal of the original pressed-in metal “fitting band” in the reservoir body, but does not require the use of gasket maker/adhesive for installation. Includes a replacement cavity o-ring. Each:
$ 7.95



Replacement Glass Fluid Level Windows:

Our replacement precision-ground flat mineral glass window is a simple and durable upgrade to the original style plastic windows, and are “glued” in place with an RTV adhesive that will stand up to brake fluids. Although there are probably lots of brands of gasket-maker/sealant material that will work, we've found one that is black, easy to work with, and is impervious to brake fluid (NOTE: if you're going to try to use some gasket material that you have sitting around, make DARN SURE that you test it to see whether brake fluid attacks it or prevents it from hardening (almost none of the major gasket-maker materials have been "tested" by their manufacturers against brake fluid, since you do not normally ever use gasket-sealant material in a brake system).

Note that our replacement glass windows do not require the removal (nor should you!) of the original metal “fitting ring/band” that is pressed into the reservoir body.


NOTE: There are two different types of master cylinders that were used on XJ-series bikes.....externally, they both look the same and are marked identically on the outside, so there is no way to tell them apart in that regard. But they differ greatly in the manner in which their SIGHT WINDOW was attached, and also in the size of the sight window used:

a) Master Cylinder Style A has a PRESSED-IN sight window, and would use our replacement HCP1074 glass sight window.

Identification: this style of original plastic sight window mounts completely flush with the outside of the master cylinder body, and is fitted into a very thin, pressed-in metal bushing that is visible on the external face of the master cylinder. Inside of the master cylinder reservoir, there is no visible part of the sight window present, and there is usually a thin metal disc with a thin slot cut into it that is behind the sight window.


b) Master Cylinder Style B has a C-CLIP retained sight window, and uses a rubber o-ring to seal the sight window to the body of the master cylinder reservoir, to prevent fluid leaks from around the sight window. This style master cylinder will use the HCP9819 replacement glass sight window.

Identification: this style of original plastic sight window protrudes out, away from the external face of the master cylinder body, by about 1/8". And on the inside the master cylinder reservoir, there is a large u-shaped metal clip that retains the plastic "snout" of the plastic window.


We do offer a visual guide that helps you to properly identify which style master cylinder (and thus sight window) that your master cylinder is equipped with; please review this to help you determine which one you need:

HCP17201 Aftermarket sight window O-RING. For use ONLY with original master cylinders that use a pressed-in plastic sight window. This is the o-ring that seals the sight window bushing to the inside of the master cylinder body. If your master cylinder is leaking or weeping fluid from the sight glass area, this is what you need to replace. Good idea to replace this item as a precaution during a master cylinder rebuild, but, you must remove the original sight window to access it (which typically destroys the original sight window!), so it's a Catch-22 situation. Although you can use this o-ring with our replacement HCP1074 glass window, it's not really necessary (since the replacement glass window will be glued in place).

For the Style "B" Master Cylinders:

HCP9819 Aftermarket front and rear brake master cylinder glass brake fluid level SIGHT WINDOW, correct size and thickness crystal-clear mineral glass.

$ 9.95

HCP9830 Aftermarket sight window O-RING. For use ONLY with original master cylinders that use a c-clip retained plastic sight window.

If your master cylinder is leaking or weeping fluid from the sight glass area, and you continue to use the original plastic sight window, this is what you need to replace.

FRONT MASTER CYLINDER BRAKE LIGHT SWITCH:

NOTE: except on the XJ750 Seca and XJ900RK models, the removal of these switches from the master cylinder housing seems like a trick Chinese puzzle, until you figure it out.....there is small, round hole (about 2mm diameter) on the forward side of the housing where this switch plugs in. Using a small screwdriver or other such object, gently push in through this hole onto the plastic "tooth" that is part of the switch housing, while also pulling back on the switch. Releasing this ratchet tooth will release the switch from the housing, and out it comes! Here's a good image of it:

FRONT DISC BRAKE CALIPERS and CALIPER REBUILD PARTS:

Stopping fast has never been easier! We offer a complete line of “Bolt On And Stop!” fully rebuilt original calipers that saves you time and (usually) an incredible amount of effort in dealing with rusty or stuck pistons, missing parts, etc. (the typical “restorer’s dilemma"). These calipers are professionally rebuilt, freshly powdercoated, and ready for a quick installation, bleeding, and you’re “back on the road again”. Our rebuilt calipers feature all new pistons and seals, and a variety of new or re-furbished hardware (including mounting bolts and washers, etc.). Pads and pad shim plates (those “anti-squeal” plates on the back of the brake pads) are not included and should be ordered separate.

All rebuilt calipers are sold on a trade-in basis, and a CORE CHARGE is included on the initial purchase, which will be refunded to you upon the return of same model, re-buildable calipers (and mounting brackets, if your bike originally uses those). “Rebuildable” means: no missing or damaged / road-rashed / etc. caliper bodies, mounting brackets, or hardware; no stripped threads or broken-off fasteners or bleeders; and no “ovalled” holes or passages on the mounting points.


For the do-it-yourselfer, our line of OEM and aftermarket BRAKE CALIPER REBUILD PARTS allow you to replace the operational parts needed to correctly rebuild one caliper. Available both as individual parts, SEAL KITS, PISTON AND SEALS KITS, or CALIPER COMPLETE REBUILD KITS, these precision made parts will allow you to correct restore the operational efficiency of your disc brake calipers to like-new condition. Please note that if you find that the piston needs replacing, you should be sure to check the condition and roundness of the caliper bore, and re-finish or replace the caliper if necessary.

Additionally, you should always carefully inspect and replaces as needed the various CALIPER HARDWARE pieces.....bolts, pins, rubber boots, alignment shims, and the like.

Finish up your caliper rebuild with an original style bleeder screw or the speed-bleeder screws listed further below.

Yamaha recommends that your brake calipers be rebuilt every 2 years.


HINT: one thing that the service manuals don't mention is that after all these years of abuse (and probably neglect), that the recessed fluid and dust seal ring lands in the caliper body have probably accumulated an awful lot of built-up vulcanized rubber debris and what-not, and unless you get those ring lands zestfully clean and completely free of all of the built-up junk, your new piston seals will not seat properly and will not seal properly (or, will cause the piston to jam within the bore as it is pushed "sideways" by the bulging, uneven rubber seals)....please review these pictures and procedures on the 2nd page:

fh211) These miniature radial wire-bristle brushes allows you to clean out and polish the dust seal and, especially, the fluid seal grooves in your caliper bodies using a standard dremel type of rotary tool. NOTE: please always wear safety glasses when using these brushes, as the brass wire bristles can (and do) come loose occasionally from the brush, and they'll always head straight for your eyeball when they do!

HCP15536 Aftermarket RADIAL BRASS BRISTLE-WIRE BRUSH is a properly sized, miniature brass brush that is both small enough, gentle enough, yet abrasive enough to remove the rubber debris that builds up in the caliper fluid seal groove. Failure to remove such build up leaves an uneven surface for the new fluid seal to seat against......sure to cause either immediate or longer-term performance problems. 1/8" shank fits into most standard dremel tool collets and allows you to make quick work of the polishing of this area before the installation of your new rubber seals.

HCP15924 Aftermarket RADIAL BRASS BRISTLE-WIRE BRUSH is a properly sized, miniature brass brush that is both small enough, gentle enough, yet abrasive enough to remove the rubber debris that builds up in the much thinner caliper dust seal groove. Failure to remove such build up leaves an uneven surface for the new fluid seal to seat against......sure to cause either immediate or longer-term performance problems. 1/8" shank fits into most standard dremel tool collets and allows you to make quick work of the polishing of this area before the installation of your new rubber seals. NOTE: not needed on XJ650 Maxim, XJ650 Midnight Maxim, 1979-81 XS1100 Special, XS1100 Midnight Special, or XJ1100 / XS1100 Midnight Special rear calipers (since the dust seal on these calipers fits external to the caliper bore).

Each:

NOTE: How to determine the proper clearance between the caliper body and the retainer block (with a special cameo appearance of the HCP18471 retainer pin):

- Under braking, the braking force is transferred from the caliper body to its retainer block via the large flat surfaces the shim plates ride upon. There will be zero clearance; but you don't want the retainer pin bound in the process…….the braking force has to be applied to the plates not the pin.

If you take a caliper body and its retainer block and clamp them firmly together without the shims of shim plates installed, you won't be able to push the pin through; likewise, if you put the pin into a set without the plates and clamp it together, the pin will bind.

Now add the plates and clamp it together, and the pin should be free to slide in and out without binding. Therefore the two pieces will not "bind" at the pin under braking. The proper amount of clearance (or, the proper thickness of shims needed) is however many it takes to minimize caliper body-to-retainer block clearance without causing any pin binding.

This situation emphasizes the importance of not mixing-and-matching calipers and retainer blocks; they need to stay as a matched set. An improperly matched set can be corrected with the proper thickness shim plates, but the person doing the matching would have to understand the function of the shim plates as outlined above.

NOTE: Most parts suppliers offer the XJ750 Seca caliper seals kit for the XJ650 Turbo/XJ750 Maxim/XJ750 Police (37H) model calipers, but those XJ750 Seca seals......particularly the all-important fluid seal......are different from the XJ650 Turbo/XJ750 Maxim/XJ750 Police (37H) style calipers and their seals. The difference has to do with the front-to-back thickness of the seal.......the XJ750 Seca seals are THINNER than the XJ650 Turbo/XJ750 Maxim/XJ750 Police (37H) seals, and thus the use of such seals will create a "rolling" effect as the piston moves in-and-out of the caliper bore. be aware that this difference could create a potentially dangerous situation, and therefore we only offer these correct (although slightly more expensive) seal kits for the these applications.

FRONT DISC BRAKE CALIPER BLEEDER SCREWS:

bp72) OEM and aftermarket disc brake caliper BLEEDER SCREWS, in both the original style and the improved "speed-bleeder" design that allows one-person bleeding. Speed bleeder valves (screws) have an internal spring and ball "check-valve" that allows to fluid to flow out, but prevents air from being drawn back in, thus simplifying and otherwise time-consuming procedure.

Bleeding brakes on motorcycles can be a "challenge" due to the small size of the brake line passages. Here's some tips to keep from pulling your hair out:

NOTE: speed-bleeders should NEVER be used when first re-filling a "dry" brake system----one where the lines, calipers, or master cylinder has been rebuilt or changed, for example----as the air in the system will compress, and the speed-bleeder valve will prevent fluid from flowing through the system. Always bleed dry systems using standard bleeder screws first, and only then install the speed-bleeders, and re-bleed!


for all XJ-series and XS1100 models EXCEPT XJ600 Seca II, XJ650 Turbo, and 1981-84 XJ750 Maxim and Midnight Maxim models:

NOTE: these bleeder screws also fit all of the following non-XJ series bikes:
