You have to turn the pistons and screw them in on some models. They have spots where u line up the tool and turn. Some are right handed and some are left so off its not gpinflg in one way, turn it the other direction.
If a piston is jamming in it's bore you may get it to retract, but it will never give satisfactory operation. You'll wind up changing it in short order.
@@TheTriumphGuy101 I spray it around the pistons, usually when pistons don't wanna go back or just keep retracting out I spray it a bit and it always goes back (unless the caliper is back then it'll be impossible)
