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.
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.
To push the piston back in the caliper of a 1995 Mercury Tracer for new brake pads, you can use a C-clamp or a brake caliper tool. First, remove the wheel and then the caliper. Place the C-clamp over the caliper and position the clamp's screw against the piston; as you tighten the clamp, it will push the piston back into the caliper housing, making space for the new pads. Ensure the brake fluid reservoir is checked to prevent overflow during this process.
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.
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.
