I ordered my disk- disk kit for my 67-72 c10 a wile back along with uppercontroll arms and a new steering column. I have finally made it to the portion of my build where i need to flow fluid through the brakes. I had a very difficult time getting fluid to the wheels so I purchased a vacuume bleeder and it worked better but I noticed a problem when I would hook the vacuume bleeder up and pump some vacuume with the bleeder closed it would draw out fluid. So I figured the bleeders were shot. When I pulled them out you can see the taper on the bleeder was off center and concave. Purchased new bleeders and still pulling fluid out with the bleeder closed out of all 4 corners. So I would say the calipers are crap too the counter machine must be off. Is there anything CPP can do for me. Or is there a cross reference number to buy these caliper from a local auto parts store?
