Just installed freshly rebuilt calipers with new pads and hardware on my '74. Now the pad closest to the inside of the car seems to be rubbing on the rotor. I was thinking maybe I had the spreader spring installed incorrectly, but I can't even push the pad back any further by hand either.
Any thoughts on what would cause this?  |

I can see the pins aren't fully "home"but that won't cause it,are you brake hoses good or are they new ?. Old brake lines can swell inside and cause this problem,they can appear fine on the outside . I have different brakes but they dragged on the pads ,bleed all 4 corners several times and the problem went away, try repeat bleeding. The only other thing could be the piston seals ?,are they the correct size if not the pistons don't retract after system pressure is released, remembering they only move a very small distance, good luck. |
