How do you put a piston back into the caliper?
To successfully push back the rear caliper brake piston, you will need a simple tool such as a plier or a screwdriver. You need to twist the piston clockwise; clockwise will spin the piston inward into the housing itself inside the caliper, and then you will be able to change your brake pads.
How do I reset the rear brake caliper piston?
There are two ways to reset the position of your caliper pistons. The easiest way is with the brake pads in situ. Simply push a flat blade screwdriver in between the brake pads and twist. This will separate the brake pads and, in turn, push back the pistons to the reset position.
Why can’t I push the caliper piston back?
The piston has to be pushed directly back into the caliper, any additional force on one side of it will cause it to bind up and not go back into the caliper. Try getting a big C-clamp and then using the plate from the old brake pad to push down directly over the piston.
