Furthermore you can find front brake discs in the original look and with a hole On FRONT brakes, as I have noted in this article, it is often perfectly OK, and even better on some bikes, models, years, to use the original master cylinder when adding, perhaps, a second disc to the front or changing a single spot caliper to a dual pot caliper on a one disc bike. Find Used Bmw R 100 1995 For Sale (with Photos). The early O-rings of 10 x 2 will NOT fit nor work with the later cam. A system is usually bled & fully-flushed by using up several liquid ounces of brake fluid ....which is MORE than just the initial amount of fluid in the MC, so you must replenish the fluid. A noticeable improvement in braking is had with Meonite cast-iron rotors, but I do NOT recommend cast iron over the stock material, & it is not easy to find (one Canadian producer? You will need: Use the last version of the ignition module. Some brake kits come with a tiny tube of the stuff. for /5 /6 /7- models, R45/65 to 1980. DOT4 is usually good enough even for amateur racing. The front brakes lines has been replaced with stainless steel brake lines. h. 07 11 9 919 112, plug, for the right side of the 'distributor'. Just doing the master cylinder piston size change may be enough for you. Swapping can be done for both sides, using the Left-Right, as described above, and reversing for the LEFT side of the Airhead (that means using the RIGHT Oilhead caliper at the LEFT airhead side). If things are poor, you best purchase a brand-new caliper, unless you KNOW what you are doing, or can follow directions exactly! They have an advantage for some types of racing where high brake use, ETC., will possibly heat the brake fluid to very high levels; they are also sometimes called DOT5.1. DO NOT operate the lever with such low fluid in the MC. AFTER 09/83 on some models and 08/89 on others, the O-ring became 35 21 1 457 605, which were 12 x 1 mm. SOME do as the MC piston moves over corroded areas it was not going to before. A sidecar wheel brake can make the turning radius of the rig VERY tight, essentially pivoting on the sidecar wheel (in turns towards the hack). The limit varies with the model. Add to Cart. It is VERY helpful to clean the discs on both sides with a very fine grit paper, I use sandpaper (or silicon carbide paper ..but not recommended by me for most of you). This can happen with BMW's own pads too! Thus, the pads become harder (at the near outer area), causing squealing. Cost is cheap though. I suggest you flush the system, yearly, by simply bleeding enough fluid through the system. The internal cam is not the same for both 32 & 40 mm carburetors. I use a block of wood shaped properly, to prevent the lever from coming full back (unless the master cylinder is new or newly rebuilt, then no block needed). You can afford to take your time, and try different things. The width of the tool was 0.592". Some installations use SS braided hoses and junctions or distributors, and a flexible rubber hose, not SS braided, goes from there to the wheel. ....The only things that a sidecar brake is nice for is: Holes and slots have NOTHING MUCH TO DO WITH COOLING. Water vapor can get into your brake fluid from molecular sized cracks, fittings, hoses, connections, etc. "); Another, allied problem, is that they do deteriorate FASTER. Once a DRUM brake system is in good condition, improvements are often difficult. Performance brake pads by Brembo and Ferodo for BMW R Airhead R45, R50, R60, R65, R75, R80, R90, R100 High Quality, Original Equipment BREMBO Brake Rotors for BMW R Airheads Genuine BMW Performance Front Brake Upgrade - E90/E92 325i 328i. You can't go too far with these changes, or the hand lever will come back too far. Frequent wearing parts are the brake pads. A half-hour in a humid climate might be the limit, for the total time. When you pull the bars brake lever backwards, the master cylinder piston pressures the fluid between it and the caliper pistons. That means that they absorb water vapor from the air. If the MC is a bit too far to the rear, the terminals can contact the fuel tank & cause the BRAKE warning lamp to come on, & often this is intermittent as the fuel tank can move around a bit during riding. Check that the calipers are in full working order (no sticking pistons, seals etc) and the brake hoses are not worn or cracked. For the R 100 RS and … For the 1981 and later BMW electronic ignition, modify the ATU weights slightly; use Accel coils (see my ignition article) with twin tower outputs. Problems with resealing the halves after reassembly may also happen because the originally assembled caliper bolts were tightened so much that the aluminum caliper halves distorted slightly (not all will distort from proper torque, but some will!). Once all is assembled & caliper installed & system bled, finish the job by washing off hydraulic fluid drips from the caliper with plain water. Popular Items . This definitely helps air bubbles return to the MC, as well as allowing better syringing, less spilling likely, etc. by whatever milling or spacer, etc., is needed. Model production began in 1976, with a premature shutdown and subsequent restart in 1985, and final completion of the series in 1996. Sometimes that is necessary: This type of problem can be somewhat minimized by using drilled or slotted discs and high friction pads. Best to use a fresh can each time; but, contrary to what is almost universally said ...that recommendation is NOT mandatory NOR NEARLY AS IMPORTANT as many, even some well-recognized 'experts', seem to think. The other purpose of drilling (or slots or even shallow grooves) is to help remove brake disc debris. I dislike most 'brake cleaner' pressurized can sprays, except as a FINAL cleaner. You may want to mark your wheels. Mirrors BMW … Later, BMW changed that ordering number to 07 11 9 906 328. BMW offered dual conversion kits for various models. Click on the relevent tab to view your parts. One method of doing this to allow other calipers, that I have not yet tried, is to weld mounting tabs. Working on brakes is serious business. BMW R100 RS (1980) Fork and Brake upgrade? 1981-1984 (to 3/1983?) All sorts & types of conversions have been made to 'upgrade' brakes. e.g. I used two pedals (details, photos, on this website) with a simple design that allowed just the right amount of progressive braking, withOUT a hydraulic tie-in to the tug's systems. You MUST have a system with no air bubbles in it; and you MUST have pistons that retract properly, and you MUST have CONSIDERABLY WORN PADS, all and more to even think about using these. This is another reason to use Teflon tape on the bleeder threads ...you do NOT want any possibility of sucking in air as the lever is released! ), which matches up the pad and disc irregularities; then more aggressiveness as miles are accumulated. From Germany +C $38.62 shipping. Yes, you could convert to a Japanese bike multiple spot caliper(s), they are often cheaply available. It MIGHT happen eventually, but I have seen MANY ...probably MOST ...that went 1/4 million miles & are several decades old, that were still installed and still fine. Sometimes markings are on the disc. It is easier to see the fluid color if you use clear plastic tubing when bleeding. That tiny hole supplies the system with fluid, and allows fluid to come back when the lever is released. Your discs are thin compared to car discs, and they are not cast iron, and they won't like excessive heat. NERDY: The U.S. Government specifications for brake fluid, FMVSS 116 (guess what DOT means with regards to 116) do not dictate the chemical composition of a given classification, or "grade" of brake fluid. The high pressure of the pads against the disc has now been released ...but there is still too much friction contact for a full-enough release! I am well-aware that is controversial ....especially if you are in the business of SELLING new discs! BMW R100, with variant models designated by T, S, CS, RS, RS Classic, RT, RT Classic, TIC, R and GS is a BMW motorcycle series, using a two-cylinder four-stroke boxer engine of 980 cc capacity. You may need to know tricks & hints when using a MityVac or similar device, whether pressure or vacuum bleeding method is being used. 5. It can also be caused by irregular glazed deposits, which are usually totally invisible. BMW did the same thing when it dropped ATE & went to Brembo brakes & then went to twin discs on a single disc motorcycle. For the BMW Airheads, 1970-1995, it is reasonably easy to convert the brakes to almost whatever you want, with ONE exception. It is difficult to get reliable information about disc compatibility and wear from the various linings. HINTS: If you are changing a hose or caliper or master cylinder ...or; otherwise, 'opening' the system, you may have lots of problems trying to bleed the system properly. Top Rated Seller Top Rated Seller. Boiling point and viscosity are the most relevant properties to most users, including high performance users; but they should really be also concerned about life and corrosion protection, etc. The handlebars lever free play, which is not critical, is to be 0.16" to 0.24", as measured where the lever end contacts the casting. I HIGHLY recommend you do NOT separate halves unless you MUST. This can increase braking power a fair amount, if at the expense of somewhat poorer handling due to the weight added. The 31 11 1 454 809 repair kit for the ATE NON-SWINGING calipers, as used on early R45 and R65 bikes, do NOT contain the small square-sectioned O-ring that you will need IF you separate the halves. 4 rubber O-rings 07 11 9 906 328. Like all manufacturer's, BMW discs have an official wear limit. The gauge tool should be flat, smooth, & the thickness fairly close to the original. You might describe it as being slightly more spongy. In 1985 (may be an error, could be 3/1983) BMW changed to a full-length tube through the rear drive, & the shaft is inside that tube, & all you have to do is to be sure to grease the shaft. Sometimes this, over-all, can be cheaper! If squealing is not eliminated, do step #2. Thus, the pads can remain in contact with the disc, sometimes strongly, creating heat as you ride, due to not releasing more fully. 34 11 1 157 687. STOCK BMW brake hoses are of VERY high quality & can last a VERY long time if they are not abused. i. Procedure may still be on the Airheads.org website under Technical Tips. Brake callipers left and right 3. Grinding sometimes does not work well if the disc metal has taken on a 'memory' in the material itself. This plug is NOT needed if you have dual-discs. One of the advantages of using mineral oils is that the manufacturer now has one more variable available to enable the type of lever feel, braking power, & a few other characteristics that a glycol fluid of only one viscosity available would not offer. S A Master Sleeves Brake Repair, 33 Main Rd, Wynberg, Capetown, So. This is a two-handed operation if you do it by yourself. The front fork cartridges have been replaced with the much more consistent FAC cartridges and progressive springs. Brake fluid eats paint, NEAR INSTANTLY! Some might just do a very quick one or two brake lever pumping bleedings. Human beings do not have a lot of fore-aft flexibility nor high pressure ability in their feet in pushing downwards forwards of the ankle. They do it because changing the fluid/bleeding is faster, less fluid is often used, & they may think that doing it that way makes for a more thorough fluid change. For BREMBO (some of this is applicable to ATE): Slightly loosen the caliper halves joining bolts before removing the caliper from the motorcycle because calipers are hard to hold in a vise & it will prevent scratching, etc., the calipers. Two of the major reasons folks put on SS lines is because they think they look racy; or, they think it will fix softness in the lever, which it will if the softness or sponginess is already due to poor bleeding ....or truly bad hoses (like a blister, much more rare than you may think). The one-part stainless-steel braided brake hoses are available for R65/80G/S, R80ST, R100GS PD 88-90; BMW is quite conservative regarding master cylinder size, in my opinion. For various reasons, I often prefer a SMALL disc brake on a sidecar rig. Many aftermarket Stainless Steel braided hoses have POOR internal construction; some are so bad that the fluid return is not fast enough during multiple short-time braking efforts due to the inner tubing having too-small a diameter. Reports of disc material NON-compatibility of normal NON-race type pads, are HIGHLY OVERSTATED. Bleeding/changing fluid on brakes could be an entire article in itself; in fact, it is a long even here. I suggest you pay attention to MY ADVICE, given earlier: that I think you should TRY your old master cylinder size FIRST (be SURE bleeding is perfect!). BMW's updating & identification of the parts & parts numbers has been confusing regarding the above items. Top Rated Seller Top Rated Seller. BUT, you have little to lose in trying to use the original MC, just a bit of your labor to find out if it will be OK. Browse our BMW brake parts and wheels selection today … E32 front brakes are an upgrade for non M5/M540i, but the real front upgrades are the E31 and E34 M5. Another possible problem is accumulated carbon & rubber residue, corrosion contaminants, etc. BMW R100 R 1991-1995. If that is what you have, bleed the most distant caliper in the system FIRST. Handguards BMW R100. The thick rubber hose, whether SS braided covered OR NOT, covers that small diameter internal tube. ATE under-fuel-tank master cylinders require an adjustment, which was done with a special U-shaped flat metal tool, that BMW provided in the owner's tools. If you have a BMW model with ABS, the eventual cost to you for not bleeding the brakes will be very high. This can be fixed by using a feeler gauge & very slight brake lever movement ...to see if the cam is contacting evenly across its surface, & if not, filing the shoe metal to match perfectly. Move your foot and see what angle your foot can actually reach, as you are pressing the pedal. Frozen or jammed pistons; high pad friction with brakes not in use; retraction problems, etc: You might find your brake caliper pistons jammed; or, partially so. With high stiction due to misaligned or bent/twisted forks, or improper use of a fork brace, you have a double whammy on handling. Ask him about sending your drums. e. two each 07 11 9 963 072 crush gaskets for the banjo bolt. >>>I have seen something happen a few times over my lifetime, so I offer this warning: I never bothered to write down all the kit numbers.

Failure to change nearly all of the fluid by properly bleeding the brakes may eventually cause the brakes to bind, seize, & MIGHT toss you over the handlebars. Just one of the reasons various leverage charts are NOT usually accurate for us, whether or not we are on a 2-wheeler or a sidecar rig, and this is especially so for the rear brake. BMW R60 thru R90, R100 and R120 motorcycle brake master cylinder. Some aftermarket sources have brackets specifically designed to allow the mounting of multiple-piston brakes to your bike. Any brand of DOT4 is also likely going to be OK, EXCEPT that I recommend one NOT purchase super performance brake fluid that typically says "racing" or similar, on the container. All these AND MORE considerations are why 'charts' have to be used with experience and a fair amount of knowledge, and may often be totally ignored! Your bike is YOUR bike. Slip the box-end of a 7/16" short wrench over a clear piece of plastic tubing that fits SNUGLY to the caliper bleed port valve (old hardened plastic tubing is NOT a good idea, if just the end of your tubing is hardened, cut off a piece). That can create a one-way valve because of the huge pressure differential between squeezing the handle and releasing it. If the new SS line owner now bleeds properly and thoroughly, compared to what wasn't done previously, installing SS-covered lines can greatly improve braking feel (if reduction of sponginess means anything). You can use the stock Oilhead brake pads. BMW standardized for leverage position ....but there IS a noticeable difference between the ATE under-tank MC and the on-bars MC, so be very cautious about changing to larger piston sizes. Do moderately strong stops for first 100 miles or so, & then the brakes should work OK, but DO follow pad maker's instructions on break-in. €0,-Wishlist Wishlist. Luka has switched the suffix from RS to RC—from Reise Sport, … ABS is another big question. Pads tend to squeal from localized, usually small, areas of the pad where the surface has chemically & physically changed, just call it carbonized/glazed, whether or not you can see any visual change. Nerdy: A seldom talked about characteristic is that because of the chemistry, DOT 4 fluid will have a more stable and higher boiling point during the early portion of its life, but ironically once the fluid does actually begin to absorb water its boiling point will typically fall off more rapidly than a typical DOT 3. Skip to Content. You can assemble everything together with steel brake lines and for a vintage style with modern performance. If you start upping the horse power on your bike then you will need to upgrade your brakes! These may incorporate a float switch, whose purpose is to illuminate a brake failure light if the fluid runs low. Batteries. If you change the master-cylinder bore size you also change the feel & effect on the brakes ... per hand pressure amount. ASK for SPECIFICS! These places DO NOT have to show leaks, in order for water molecules to get into the fluid. Push back ONLY enough to enable the pads to be changed! ), & put them lightly against my rotating wire wheel which cleans and burnishes them smooth. It is acceptable for most folks though,& increases braking ...with no problems that I know of ....except a tendency to be a bit grabby at first (sometimes when wet, high humidity conditions), and to take longer to break-in. 6. If the mounting hole center to center distance is the same as your Airhead mounting holes, this is going to be a relatively easy job. Your cussing vocabulary is expanding. There are rare instances of disc brake pads that appear to expand with age. WHY DOT3 or DOT4 fluid? AVOID hydrocarbon solvents other than brake cleaners. Split caliper halves ONLY when really needed! I also have other thoughts, perhaps better not mentioned here. 1981+ rear drum brake pivot shafts: The shaft that has the O-ring(s), will not accept the O-rings, & it will be difficult to install them, if the diameter measured at the bottom of the grooves is not a minimum of 10.41 mm. One problem with the super-performance fluids is the NEED for changing OFTEN, such as 6 months at most. REPEATING A CAUTION: Brake fluids EAT paint. When I rebuild a brake caliper I use liquid dish detergent and water, sometimes with small brass brushes, all followed by flushing well with water, then either baking for an hour in my oven (around 200 degrees Fahrenheit) or letting them dry for a day or three. REVERSE pressure methods, using a tool that applies fluid under slight pressure to the caliper bleeder valve, may help in egregious bleeding cases, but may force dirt/sludge upwards into the system. The 304 SS material will work-harden, then can break; also the bad braiding area can rupture ...& you get a bubble situation that can blow out. 1 each 25 mm shoe 34 21 1 242 403 If doing the overnight thing, release the lever in the morning, and then leave the lever alone! You should, yearly, bleed the brakes more than just the point that fresh new clear fluid comes out. I recommend common SANDPAPER, and NOT emery paper or silicon carbide paper. New customer? If bolt is 40mm, please use BRA10493) and a sachet of brake assembly paste. ALL legal disclaimers here! They are touted to eliminate squealing. As previously noted, I suggest you leave a bit of fluid in the bottom depressed fluid area. We have found 9 All Products, 6 Pads, 2 Discs and 1 Shoes. Besides deteriorated parts from failure to bleed regularly, the most common reasons for these things is a kinked inner tubing inside the brake hose, often caused from hanging the caliper by the hose instead of a bungee (or, rarely, a VERY old & deteriorated brake hose) .....and/or, a plugged fluid return hole, which is quite small and is located inside the master cylinder at the bottom, usually in that little depression place. ...that means the holes, the outer disc surfaces, & using very fine grit sandpaper prior to the final solvent cleaning of the holes & flat surfaces. YOU MAY NOT find these numbers in USA fiche: I have used pieces of old very thin feeler gauge material which are steel. 10. NOTE that all bikes FROM 1987 should already have these modifications. See (b) and, especially, (c). A common “upgrade” to the pre-Brembo brake models is to replace the ATE under the tank master cylinder, fluid reservoir and front brake cable with a handlebar mounted master cylinder and … Handlebars. Some pad types, particularly in the past, were not compatible with BMW discs ...but I have not seen that problem at all in recent years, probably due to more careful selection of materials for our bikes; that is, the pad makers have recommendations that are correct. Those places RARELY ever leak noticeably! Most liquids do not compress, although bubbles of air or liquids in gaseous state certainly will. The fix is to resurface the halves on a surface plate with some 1000 grit Wet-or-Dry paper, using wetted paper, water is OK. You can start with slightly coarser paper. You can try http://www.vintagebrake.com. R2V-GS 1991-* & BASIC; R2V *-9/1984; R80ST; R2V-GS 1988 - 1990; R80/100R Paralever; /6 /7 *-9/1980; R100R The kit is 34 21 1 237 234. View Product. That is the ATE swinging calipers which use special fork lowers. Use of "HH+" rated material will produce better braking with less pressure needed at the handlebars, with the usual caveats on braking use. OFTEN you must have things vertical. It's all messy, due to the various models, when the change was phased-in; and BMW seems to have not followed its own published information all that well either. When you are done, and the MC filled to BELOW the max fill line, cover tightened moderately, any bellows installed first, then clean the MC area with a wet rag. Discolored tubing at the bleeder port(s) can influence what you are looking at. Only a bit of milling was needed on the caliper in this 'easy' installation. Note also, that the first bleed, or second, is required to fill the plastic tubing that goes upwards some, to an inch or more of fluid, so be careful to close the bleeder port valve early, because releasing the lever will try to suck-in the old fluid, or if not enough, AIR! The fluid has anti-corrosives to deal with this, up to a point where the water is at a high enough percentage to cause corrosion. I was pretty proud of myself when I figured out how stupidly simple (in theory) it was to do progressive but limited sidecar braking ....and this was with great brakes too .... if the design was done really right. These square O-rings have been known to get hard with age ....but it is the corrosion in their associated caliper groove & perhaps a corroded piston that are typically the main problem. The 4 pot caliper uses 32 & 34 mm pistons. If the piston is badly pitted it MUST be replaced. SS lines can cause a lot of problems. Have a wet rag already in place there to catch the fluid, do NOT let it get onto the brake pads, wheel or fender paint work, etc. For longest brake system life, your brake fluid probably needs yearly changing, as it attracts moisture, right through the NON-leaking lines fittings areas & air enters the master cylinder bolt & screw fastenings, etc. Use the stock BMW upper brake hose, don't use an uncovered SS braided hose. You need to mill about 4 mm off the mounting surface; the larger piston then becomes the leading instead of the trailing piston, leading to weird wearing patterns, but a substantial braking improvement. I've done some of these things. If the diode shorts, & you are also low on fluid (which activates the switch), the starter could theoretically energize! Michael Morse at The BMW is a first generation R100 RS. EITHER brake pedal could apply the tug's Ural drum brake. I did my own version of a 100% mechanical brake on the sidecar on my R100RT-Ural rig. More subtle, & seen more often, is to have them not retract as well as they should, which lets the pads stay in contact with the discs with too much pressure when they should hardly, just barely if anything, be touching. To accommodate humans, most rear brakes on motorcycles have a limited maximum pedal travel from no brake, pedal at rest, to full brake. ) the 'feel ' of the series in 1996 wooden feeling '' can be very dangerous identical spacing.
