Hello all I got my kingpins and bushings done adjusted the sector drives like new now on to the brakes I planning on rebuilding the hydravac reman in Atlanta has the parts and having them reline the park brake shoes. As it is right now u have pump the brakes a few times to stop It's losing fluid through the booster I hope the rebuild will fix that no wheel cylinder leaks and the shoes look good I guess my ? Is what size bore should my master cylinder have the guys I bought the truck from had put a new one on I wonder if they put the right one on I'm also planning on replacing lines and hoses all you guys that order from rock auto how are y'all looking up big bolt parts if I do a parts search for a 6500 all I can find are parts for a one ton down Thanks in advance Kip
