Hydraulic force, transmitted by the brake fluid.
Use a "C" Clamp to fully retract the piston into the caliper body
Yes, you need to remove the caliper first, then use the old brake pad and a C clamp to push down the piston of the caliper.
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
Use a 6 inch c-clamp.
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.
You have to have a air compressor to do it. Take an air gun and insert it in the hole on the caliper were the brake line goes to it. Then take the piston in one hand and start it in the caliper while you are blowing air into it and the air will push the rubber boot out around the piston as you push the piston in. It is alittle trickey, But that's how you do it.
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.
Use a C clamp to push the piston out of the way to remove and also to place back on rotor.
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.
In most cases, no, however if you are having issues getting the piston into the caliper, it may be seized, or it may be a turn 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.
