![]() To do it properly you need to remove the front calipers. Rosie, no, your bike does not have the nasty Servo ABS system of 2002 through 2006, You can bleed from the handle bar or rear reservoir to the calipers. ![]() Pretty straight forward job.if you know what you are doing. Then do the right.Īnd you are supposed to push the pistons back into the calipers and hold them there.I never did, and it always worked for me. The Servo Pumps are then going to slowly.and I mean really slowly.draw the fluid out of the funnel and push it through the brake lines to the calipers/bleed nipple.ĭo the front left caliper first, don't know why but thats what BMW says in the maintenance manual. No need to pump on the lever, just let the pumps run. Then, pull on the lever until the Microswitch turns the Servo pumps on and hold it there. When doing the brake circuit, insert the funnel into the ABS unit reservoir and fill it to the top. Just gently push the fluid through and keep topping up the reservoirs (Handle bar / rear brake). Next time use clear brake fluid again.ĭon't turn the ignition on when doing the "Control circuits". Its blue in color and you can then see if you have pushed all the old fluid out. I mistakenly was opening the rear nipples and was wondering why there is no fluid coming out when pumping the handlever.īuy Bendix DOT4 Brake fluid. Make sure you know which bleed nipple is for what circuit. The seal is about a 3/4inch or 20mm diameter.Īnd buy yourself a couple of feet of clear hose.Makes the job less messy.

After I had clear clean fluid coming out of the wheel cylinders I closed the system and everything works fine 4 months later and 5000 miles. This ensured I would not ruin the seals running the servo motors opcorn. ![]() I therefore vacuum pumped the old fluid out of the servo. I know from bleeding brakes on anything else that you do not want to run the master cylinder past it's normal range because the seals will get destroyed when they run across the corroded metal in the master cylinder. Specifically the dealer will bleed the wheel circuits of the servo by running the servo's motors to force the fluids out past the wheel cylinders. ![]() Dealer does pay for a servo that fails so it has no incentive to change its procedures. I think the dealers method is the very thing that causes the servos to fail. There is a link on this site that shows the dealers method to bleed the servo. I was lucky enough to see the tech bleed another bikes servo which did turn out bad a did need a replacement servo. I had been ignoring the dealer advice to flush it every two years for $350 plus.įinally dealer said that he was pretty sure that when they flushed it that I would need to change the servo motor at a cost of 1800 parts plus labor. Everything was squared away, and that DET beat all the others when it came inspection time, which included a drill to assemble and test weapons.I recently flushed my brake fluid for the first time on my bike. When I first showed up, the CWO-4 pulled me aside and told me how things worked there: get there at 0600, work hard and work smart, get done by 1100 or 1200, and then GTFOT and enjoy Hawaii for the rest of the day.
