He all. New to the site. Got an issue I can not diagnose. Truck is a 95 K2500 with the 8 lug, 13 inch brakes with the 8600GVW. I have a BAD hop under heavy braking coming from the rear. Cant feel it in the steering wheel or brake pedal, but you sure feel it in the seat. I've replaced wheel cylinders, shoes, drums, all adjusters and springs, shocks, bled the system, etc. No brake or ABS light on the dash is on. I've disconnected the ABS fuse. I have it narrowed down to the rear drivers side. I can pull the wheel and drum off and back in the adjuster. No hop. Once the self adjuster starts getting back to where it should be, it starts hopping again. Been trying to fix this for over two years. Its driving me crazy. Any help/tips/info would be greatly appreciated.
