Anyway my brakes are acting up, my good friend though I either need to adjust the rear drums on my 14BFF or replace the master cylinder, I have the cylinder swap down, but how do you adjust the brakes, something about sticking a screwdriver in the small slot on the back of the drum, jacking up the axle and spoinning the tire till the pad contacts the drum? Anyway how interchangeable are master cylinders? I have a 78 cab and 85 front clip, the guy who built the body said it was an 85 half ton cylinder. So what the hell am I to do eh? I hate the NAPA man now because hes an ugly opinionated condecending and overall not nice degenerate of a worthless human being who deserves to die, and as such am going to order my MC online. So anyone with an 85 half ton or a 78 3/4 ton who has replaced their MC tell me whatcha got ok? Hey thanks a lot, I appreciate your time!
