fyi, i was not able to get the piston dust boot on the way the fsm says to; i was able to get it on by first putting the piston boot into the cylinder body (aka caliper's piston hole outer edge/rim) and then putting the piston into the dust boot & then install piston. i would help to have an extra pair of hands and securing the caliper is also beneficial. basically, you just have to get the boot started on one side of the piston and then pull/stretch the boot around the rest of the piston. some smallish s type hooky things help aslo. getting this boot over the piston was the toughest & most time consuming part of the rebuild.
