They make a tool to push the calipers in and can be bought at most auto parts stores and some will rent them. Some people use a c-clamp to push them back in.
The brake caliper piston may not be retracting properly due to issues such as a seized piston, worn out seals, or air in the brake system. These issues can prevent the piston from moving back smoothly, affecting the brake performance.
You will need special brake caliper tool such as a C-clamp to push back the piston on the caliper of a 2002 Mitsubishi Lancer.
To compress a caliper piston, you can use a brake caliper tool or a C-clamp. First, ensure the brake fluid reservoir cap is loosened to avoid pressure buildup. Then, position the tool or clamp against the piston and the back of the caliper, and slowly apply pressure until the piston is fully retracted. Be cautious not to damage the piston or the caliper during the process.
There is a 14 mm bolt on back of caliper. Remove this & use a 4 mm Allen wrench to back piston into caliper.
How do you get the brake piston to retreat back in caliper ?
You will need to push the caliper piston back as well as rotated when you are replacing your rear brake pads. The caliper will need to be turned clockwise.
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.
C or G clamps.
They need to be wound back in, using a special tool, a G-clamp also work to push it back, with the rotating part on the caliper piston.
The rear brakes you need a 3/8 standard wrench to open two bolts retaining the caliper. The piston caliper requires a special tool to "wind " it or screw it back in order to install the new brake pads. DO NOT PRESS THE CALIPER PISTON BACK. You have to "screw" or rotate it.

To change the brake pads on a 2001 VW Beetle, first, safely lift the vehicle and remove the wheel. Then, remove the caliper by unscrewing the bolts and carefully take it off the rotor, supporting it to avoid stress on the brake line. Replace the old pads with new ones, ensuring they are properly seated, and compress the caliper piston if necessary. Finally, reinstall the caliper, secure it with bolts, put the wheel back on, and lower the vehicle.
on the caliper take out the bottom bolt, there are two bolts that the caliper slides on and only undo the bottom one. Then the caliper will swing up and allow access to the disc pads . You need to get a G-clamp and push the piston in the caliper back( or else it wont fit back down). put it back together and pump the brakes to set the brake piston b4 you drive or the first time you go to brake you wont have any.
