914World.com _ 914World Garage _ Rear brake leak

Posted by: J123young Oct 15 2017, 04:50 PM

So I have a slow leak driver side brake caliper on the adjuster. It doesn't matter if I turn it all the way in or all the way out. It still leaks a little. Especially after driving. I think I'm missing a washer or something that goes around that adjuster to hold it in place and maybe also stop the leak. Any help or suggestions would be awesome.

I had the same thing a month ago. Eric Shea told me the small O ring on the adjuster, inside the caliper, hardens up after 40 years. I put on a set of pmb restored calipers to solve the problem.

Do you have 2 leaks or 2 threads .
Don't drive till fixed ok,no leak @ brakes is ok .

Looks like the small C clip on the adjuster screw is missing. That could be the source of the leak by not keeping the screw pull snug to the caliper housing.
