Master cyinder losing fluid from cover
I have a disc/drum set-up, 7" booster with 82 Corvette master cylinder. I replaced both rear wheel cylinders and now have brake fluid leaking past the gasket between the lid and the body of the M/C when the car is driven. It was not leaking before I replaced the wheel cylinders. The system also has a prportioning valve which I suspect may somehow be the culprit. Any suggestions on what to check would be appreciated.
