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?  |

Bleed the brakes again, if the piston won't stay in you may have air in the system

Then if you are pressing the piston in and it is coming back out (more than 1/16") then the system is sealed and the air pressure is pushing it back out. Nothing to worry about - unless the system is supposed to be open and the air is getting trapped when it should not be. Open the bleeder and do the experiment again. |
