I need help with my braking problem. It pulls to the right big time, enough to make a right hand turn without moving the steering wheel just with the brake. This is what I have done related to fixing the problem. Please tell me what I might be overlooking. Both calipers replaced, both brake hoses replaced, all balljoints replaced, alignment, new rotors, pads, guide pins, rear seals replaced because the shoes were saturated on the left side. I really thought this was the culprit, but once again I was wrong. The left caliper actually has been replaced twice, just to verify that the reman calipers that I got at Autozone were working. No difference at all. Re-man steering box. That's about it. I have all polyurethane bushings, Rancho 9's, 4" lift, BF Mud T. Does The Prop valve affect Left/ right ever or just Front/Back. I'm hoping that this is somewhat common with Blazers, but so far 2 brake places and one dealership has failed in figuring this one out. Please help.
