I did not adjust them i thought with pressure from my foot they woul go back in as the front pistons do. I had a friend say that i could have air in the system because the little allen screw thing fell out when i hung the caliper from the shock assy.
Just did all 4 brakes on my 03 p5 auto and now my ebrake doesn't function properly. I did retract the piston using the allen screw under the 14mm bolt. When i have my foot on the brake and i pull the ebrake i feel pressure apply opposite against my foot. Any help woul be greatly appreciated.
