C4 Brake problems!!
Hi all...
Seems like a grate place to be
I´ve had a serious brake problem on my "86, for years now.
The heat expansion of the brake fluid does not seem to return to the oil reservour but does instead expand within the system in such way that the brakes are being applyed. As a result, I end up driving against the brakes...
I have flushed the system, machined the rotors, overhauled the pistons (twice) and changed the wheel bearings... without success.
From my understanding, the "86 is the first to come out with ABS which, in my case, has been disconnected (bad wires).
Living in Iceland, my options for corvette tech is very limited so I hope you guys can bring up some ideas that might help...
PLEASE!!!!

Did the problem come up after replacing the master cylinder or booster? You need to unbolt the master cylinder from the brake booster and shorten the booster pushrod. Get ahold of it with some good minivise grips and screw the end in a little at a time.
When it's adjusted right, you'll feel by hand a tiny bit of slop in the brake pedal before the pushrod contacts the master cylinder piston.
You don't even need to remove the brake lines to do it, pretty easy fix.
