I bought a 71 demon and the guy had changed the ft to big bolt disk, lines also, aftermarket stuff I think, he also replaced the master cylinder. Ok heres my problem the front brakes pump up and lock (full petal), so i put the car on the lift and loosen the ft bleeders and they release, a few days later they are on again with no one being in the car, is the master cyl rod to long? it,s manual brakes, anyone else have this problem?
thanks
