How To Reset A Stiff Brake Calliper - Without Putting Strain On Vital Components

[McAdamsMechanics]

Just open the brake nipple up. Should release the pressure 👍

If old, a ridge of dirt may have built up on the piston, so could be impossible to retract. Need to open, clean and refit new rubber gaskets.

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.

Would be cool if you took the words off screen so we could actually see everything…

Or just spray it with brake cleaner that always works for me

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.

Pretty useless info without the tool....
