My 52 1 Ton (or it may be a chopped down, re registered 1.5 Ton based on some oddities), has pedal issues. It has been sitting for a long time so the front cylinders that I replaced were clogged up and I replaced the rear cylinders recently. The rears were the larger cylinders that used the round discs with the knobs. One of which i replaced so I could adjust the brake. I have also rebuilt the master cylinder. We used a brake bleeding device that used compressed air to force brake fluid through the master cylinder through the lines to the cylinders. The brakes have been adjusted out to the point of a slight drag on all the wheels.
The problem is, to get a decent pedal I still have to pump the pedal, typically a sign of air in the lines. I have not found any evidence of leakage at any point in the system, and with the solid stream of fluid coming out of the bleeders, I don't think I have air in the lines. Is there something in the master cylinder that could cause this or not enough adjustment on the drag?
Anyone with any thoughts?
