my first time changing rear brake pads on 02 softail(done by dealer previously). removed wrong bolts, larger ones, and inside of caliper loosened by about 1/2 inch. fluid leaked out of caliper so I tightened 3 large bolts, then loosened 2 smaller bolts and replaced pads as I should have done in the first place. reservoir is full but pedal goes down all the way and pistons don't push out. did I ruin 'o' ring inside caliper? thanx 4 help, hog up
