Caddy calipers 14 bolt FF ?\'s I got 1976 caddy eldo rear calipers and pads, Derbinator's disc brackets, new 77 chevy 3/4 ton front 4x4 rotors and I am trying to do a rear disc 14 bolt FF swap. The problem is I can't get the piston all the way flush with the caliper body, and the brake pad will not fit. Is the caddy caliper piston supposed to be flush with the caliper body? I took the bleeder screw and the banjo bolt completely off and put in a press, but piston won't go flush. Those rotors are to thick? Also does anyone know the spring pad distance for a 97 yukon gt? That is what I will be putting this 14 FF in. It looks like I have to move the perchs out and maybe the shock mounts. Anyone know the tricks involved?
