Caliper Bushing blowout (was: Brake system warning on first start.)
Well The reason showed up.
The bushing that hold the emergency brake lever on the right rear caliper blew
out last Saturday spewing the brake fluid all over the tire and over the
(Fortunately the warning light came on as soon as the car was started and my
wife called at work to ask. I had her check for fluid and sure enough there
was some smelly and slippery... so no accident resulted)
When I took off the caliper the seals and all seemed to have gone (on a
rebuilt caliper from KVR just installed in August) the brake cable arm bushing
could be moved around about a quarter of an inch!
I'm now waiting for a new rebuilt caliper.
Has this happened to anyone before? And if so dod they determine the cause for
86 5000 CD Quattro

As long as the light does not flash when you pump the brakes, your ok.
If it does, you have to replace the brake pressure accumulator, AKA the
have experienced the same problem, it happened to be a loose clamp on one
of my hoses attached to the resevoir. The leak was real small and not
I had to feel around with my fingers, and it wasn't leaving
drops on the ground, also your pressure accumulator may be going.
