Thought I had the problem fixed but did not work the other day as it should. I replaced the flex rubber hoses on both front left and right, also new calipers left and right, new master cylinder and thought we had it fixed. Even adjusted the rear brakes. The right side locked up yesterday so guess I will have to start over again to find the problem. Fustrating.... When I had the hood and right fender repainted the other day, the painter removed the right tire and exposed the caliper and rotor. He also cleaned the engine with some kind of cleaner. The right never locked up prior to this so could it be he soaked the brake pads and that is what is causing the problem? I thought about replacing the right pads. I was told by several that the rotor would not be the problem or the compensation valve since it only affects the rear brakes. Do you think replacing the right brake pads is the next step.?????
