get a large pir of grips and squeeze should go back in.
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.
To push the rear caliper piston back, you'll need a caliper tool or a C-clamp. First, remove the wheel and brake pads to access the caliper. Then, insert the tool or place the C-clamp over the caliper with one side against the piston and the other against the caliper body, and gently tighten it to push the piston back into the caliper. Make sure to check the brake fluid reservoir, as pushing the piston back may cause fluid to rise and overflow.
There is a 14 mm bolt on back of caliper. Remove this & use a 4 mm Allen wrench to back piston into caliper.
There is a specialty tool for this procedure. There is a metal plate that fits on the piston, then a clamp for the back of the caliper. Turning a screw will pull in the caliper. Opening the bleeder valve may be necessary.
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 push the piston back on the rear caliper of a 2005 Mercury Montego, you'll need to use a brake caliper tool or a C-clamp. First, ensure you have removed the caliper from the bracket and unhooked the brake line if necessary. Then, place the tool or C-clamp over the caliper piston and the back of the caliper, and gently compress the piston back into the caliper housing. Make sure to check the brake fluid reservoir and remove some fluid if necessary to prevent overflow during this process.
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.
To compress the caliper piston on a 2007 VW Rabbit, you’ll need a brake caliper tool or a C-clamp. First, remove the caliper from the bracket, ensuring you support it to avoid straining the brake line. Then, place the tool or C-clamp over the piston and the back of the caliper, and gently compress the piston back into the caliper housing. Make sure to check the brake fluid reservoir, as compressing the piston can cause fluid to overflow.
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.
Use a "C" clamp to collapse the caliper piston. Use one of the old pads across the face of the piston. If you use the clamp on the bottom of the piston it is possible to crack the piston. Using the old pad spreads the pressure to both sides of the piston. That is if the piston is a cup. If it is solid on the face then it screws in, but I believe this type is only used on the rear brakes of cars.

if it is the caliper at the rear u need the special tool to turn the piston clockwise to push in and counterclockwise to pull out
