Yes, the "O" ring seals the caliper, but it also "bends" a but as the
piston slides though - and when the pressure is released, the "O" ring
straightens back out, pulling the piston back in just a smidge. This
gives the clearance. Take a good look at the boot, flex it around -
then try to push the piston back with your fingers. Note how little
resistance the boot gives to being deformed - and how much force it
takes to move the piston. Absolutely no way the boot could handle
pulling the caliper back.
Your instructor at Chryaler only taught you half of the story.
I've taught it too - and I've tried to get the whole story told.
