So I am rebuilding the calipers on my '63 SIII. the pistons, pads and all rubber of course. Do you know any tricks to get those darn rubber boots and pistons to go into the calipers? If you put the boot on the piston first, you cannot get the ridge into the caliper with the piston in the way. If you put the boot on first, there is so much rubber (tight tolerances) you cannot push the piston in... I'm at a loss... Help!
