I did my brakes last and found out this morning that you are not supposed to compress the rear calipers piston the same way that you do the fronts ( like with a C-Clamp) but I guess that they get compresses by rotating the piston. Did I damage the rear calipers by not turning them back to compress them or can I just go back and do this step now. It has only been driven about 15 miles. Thanks alot everyone. Your help is appreciated.
