Brakes
A new problem..... I was using my 79 with power discs to haul a load of busted up concrete to the dump.... Actually two.... It did great.... But ever since then I have noticed that when I engage the brakes to stop once I stop the pedal will drop a little stopped when I am stopped.... I don't think it did that before.... I would like to think that I damaged the mc when I was hauling.... But it could have worn out on it's own..... I am thinking I have a bad mc.....
Wanted to know how to diagnose that so I don't just replace stuff that isn't bad.... And if there is an easy swap to a newer style with the plastic resevior the old metal ones with the rubber gasket always seem to end up leaking... Thanks

That's usually indicative of a faulty MC, could also be a leaky wheel cylinder, brake line, etc. so rule those out first, do yourself a favor and spend the extra 20 bucks and buy a new MC, not a reman'd MC, there's nothing more annoying than having to do the job 2 or 3 times because you got a bum MC.

Not to hijack the thread, but I'm having similar problems. I had the master cylinder and booster changed about 2 years ago (don't know if they were new or re-man) and about a week ago I changed my front pads, rotors, brake lines and now my master cylinder is leaking. I think it is leaking around the cap seal and running down at the center of the booster. Should I attempt to find another cap or go about replacing the whole thing? btw the brake fluid looks horrible, so i'm going to bleed it all out if i can. I've never changed a master cylinder before but after spending as much as I have on these brakes I want them to be fixed right!
