on the front disk brakes there are two metal collars with expandable rubber boots on each end that the bolt go through which hold the caliper on. the top one, on each side of the car, can easily be slid in and out so that i can relube it. however the bottom one on both sides of the car do not move more than just a little bit in and out. what is the secret to get the lower collars to move. have already soaked then in PB blaster.
