Best answer, it might be. there are two basic types of calipers on newer cars: push in and twist in. If you twist a push in type, no harm is likely to occur; if you push in a twist in type of caliper, you will damage it to the point of requiring replacement.
Be certain what type is installed on your vehicle. the best way to accomplish this is to purchase or view a maintenance manual such as those published by Chilton.
If you are wanting to colaspe the piston so you can fit new pads in the caliper, first open the master cylinder, then use a "c" clamp or "c" clamp vise grips to slowly push the piston back enough to place the pads in and then fit caliper over your rotor.Keep in mind there may be a mess at the master cylinder.

Your brake piston may not be retracting properly due to issues such as a seized caliper, worn out brake pads, air in the brake lines, or a faulty brake master cylinder. It is important to have your brakes inspected and repaired by a professional mechanic to ensure safe driving.
Brake master cylinder repair is where someone or some body fixes the master cylinder on your brakes. It is the main line to your brake apparatus. Also the master cylinder is the container for the fluid and the piston, forming part of a device such as a hydraulic brake or clutch.
Make sure the cap is off of the brake master cylinder. You can use a tool designed to move the caliper or a c-clamp. If the piston is too far out it may not go back into the caliper.

use a large c clamp and push the piston back in, just be sure to not over fill you master brake cylinder because you will be pushing more fluid into it.
According to your question I am assuming you are talking about the brake caliper. If so take the lid off of the the master cylinder. (where you put the brake fluid.) use your old brake pad and you will need a C-Clamp. Put the C-Clamp in the center of the old brake pad and tighten the clamp until the caliper piston can't go back any further. Put the new brakes on go back with installation. NOTE> DO NOT push the brake pedal while the top of the Master Cylinder lid is off. PUt The lid on then you can hit the brake pedal.
take the tire off, remove the caliper, remove and replace brake pads, compress piston, slide caliper over the roter, tighten up the bolts on the back of the caliper, do one side at a time, open up the master cylinder before messing with it, its pretty easy.
Twice as much
You can use a C-clamp to compress the caliper on just about any vehicle. You might want to place some rags near the Brake Master cylinder because brake fluid will travel back into it from what is left over in the brake lines. If you don't, you will spill brake fluid onto the floor.
The master cylinder for the brakes is probably out or going out..the piston inside the master cylinder is letting the fluid bypass it. OR You have air trapped in the brake lines and must bleed the brake lines. When you step on the pedal, the air does not compress so the pedal goes to the floor. You must get all the air out of all the lines including the master cylinder for the brake system to work correctly. There won't be any fluid leaks with either of these scenarios....... ........only if you have a leaking brake caliper piston or with a drum brake cylinder, where the seals are shot, and you can see the fluid running down on the tires Don't drive it until you find the problem.
