    My master cylinder is the older style (1980) that has the lid held on with a wire clip.Any time I tilt the truck a little (often) fluid leaks out the cap.It is wrecking the paint on everything.Is this normal,or is mine faulty? Will a newer style fit,or do they leak also? Thanks.

    Something's wrong with your cap. It shouldn't leak. /forums/images/graemlins/shocked.gif Sounds like it might have a small hole in the rubber gasket. I think you can buy just the gasket. /forums/images/graemlins/cool.gif

    Thanks Harry. I will pick one up tomorrow. The original one leaked, so I replaced the entire unit with a rebuilt one, and it leaked from day one. So I thought it was normal.
