I have a '79 w200. When i press the brakes wiht the engine off, they work fine, but with the engine running the pedal gets REAL soft and goes all the way to the floor without stopping the truck (very bad thing). I've redone all 4 wheels, bled and adjusted the hell out of them. Any Ideas? Thanks in advance!
