Rear Brake Gl1100 1982

Postby martin.brown4 » Wed Apr 01, 2009 9:43 am



My rear brake is giving me problems with what I suspect is a pressure build up due to the calipers not releasing. I have rebuilt the caliper with new seals & the piston are not scored & work reasonably easily. I suspected the brake cylinder was blocked & seems to build up pressure so I have taken that apart & cleaned it out, but the problem still persists, is there a vent in the master cylinder that equalizes the pressure that may still be blocked that I have missed?

You got it - there is a tiny hole in the master cylinder that allows the pressure to release and the fluid to flow back from the caliper into the master cylinder, when the brake pedal is released. This hole is blocked when the brake pedal is pushed down, and unported when you release the brake pedal. Because the hole is very small, it can get clogged with gunk or debris. It's actually a fairly common problem, both on the front and rear brakes.

I'd recommend rebuilding your rear master cylinder, and while you have it apart, take a single "bristle" from a wire brush, and using it to ream out the tiny hole inside the master cylinder.

I'm glad to hear you stop by just to say thanks, and not just because you have problems! :)
