most caliper pistons can be squeezed in with bigg plyers after you loosen bleeder valve
Calipers can be rebuilt but if the pistons are scored caliper will require replacement
Clockwise
Make sure caliper pistons are pressed in
I just did mine. Use a screw driver to press the brake pads away from the rotor and compress the caliper pistons back some so you can remove the caliper off of hte rotor. Losen and remove the bolts to the brake caliper. DO NOT DISCONNECT the brake line from the caliper! Get you a c-clamp and a piece of 1/4 board about 4 inches long. Once you have removed the caliper from the mount and removed the brake pads support the caliper with one hand. Place the wood over the caliper pistons and using the c-clamp place it over the wood and center of both pistons and other side of caliper to compress the pistons back into the caliper. Make sure you DO NOT PINCH the rubber boots on the pistons. Once you have compressed the pistons back into the calipers install your new pads and calipers back on the mounting surface and tighten the bolts back to torque specs.
Push them in with a "c" clamp.
The Brake Piston Cube is a cube-shaped tool used to retract brake caliper pistons in vehicles when changing brake pads. Its design allows it to fit into the caliper housing and apply even pressure to retract the pistons back into the caliper, facilitating easier brake pad replacement. By turning the Brake Piston Cube, the pistons are compressed uniformly without damaging the caliper or seals.
Caliper pistons should retract if calipers are in working order. Calipers need to be removed and rebuilt or replaced. A brake fluid flush is highly recommended.
that depends if it is front or rear calipers
it should just lift off.. if not loosen the pressure on the caliper by inserting a screwdriver twen the pad and the caliper wall.. and prise the caliper open. when you have the caliper off.. use a C clamp and a slip off wood or whatever to press the caliper pistons back into the housing.. this will allow room for the new pads and any adjustments.. reseat the caliper and tighten the bolts.. when you press the brake pedal the caliper pistons will reseat themselves and you know this has happened as the pedal will go firm

Requires a tool that not only pushes in the caliper but also rotates it as it goes in.
