the caliper piston turns clockwise to compress,the gm w-bodys are known for bad rear calipers. gmjim
You can use a large C-Clamp to compress the caliper piston.
Use a "C" clamp to fully retract piston into caliper body
there are 2 ways on is with the C- Clamp. when tightening the clamp loosen the bleeder valve. the second is have to use the caliper tool to screw in the piston steve@spider-technologies.com
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.
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.

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.

with a c clamp. put a block of wood or your old pad over the piston and tighten with clamp.
Similar to any other caliper piston, you might used a C-Clamp that has been covered in some protective coating to prevent it scratching the caliper. Ideally the C-Clamp would not directly compress the piston edge but some piece of flat metal, laid out in a way that would allow it to spread the force across the piston's diameter.
When you are changing disc brake pads, you should use one of the old pads and a large clamp to compress the piston immediately after removing the caliper. This helps to prevent air from entering the brake lines.Use caution when positioning the clamp so that it does not put any pressure on the brake hose, bleeder valve, or anything other than the piston housing.If the piston is difficult to compress, you may have a frozen caliper and/or a leaky brake hose.
You can get a caliper piston compressor tool at most autoparts supply stores. Some even loan them for free if you buy your parts from them. Another option I've used is a thin piece of plywood [to protect the face of the piston] combined with a "C" clamp to press the piston back into the caliper. Usually, once the piston is fully returned into the caliper, the clamp and plywood can be removed without the piston moving back out. If it does, then recompress it, and just slightly "crack" open the bleeder screw [only momentarily to relieve the hydraulic pressure]. Then the piston should remain fully inside the caliper after the clamping pressure is removed. Good luck.
