im assuming you mean the caliper piston. they make a tool for it but you can use pliers to turn in clockwise and keep pressure on it and it will go in. you may be turning awhile but it will work.
Beside the parking brake.
brake go down and lock pad
Pressing the brake pedal and putting the car in gear will release the parking brake.

Rewind it with a piston rewind tool or, at a pinch, use needle nose pliers.
The teves caliper is a single piston disc brake caliper and the akebono caliper is a dual piston disc brake caliper. The teves caliper is a single piston disc brake caliper and the akebono caliper is a dual piston disc brake caliper.
The piston retracts by turning it back in. You will need a Disc Brake Pad Spreader (Part Number: 648412) and a Disc Brake Piston Tool (Part Number: 648410) found at Advance Auto Parts. The Brake Piston Tool looks like a Rubik cube. Simply line up the knobs into the piston slots and place the disc brake pad spreader between the caliper and brake piston tool. Apply slight pressure on the piston via the pad spreader and turn the brake piston tool with a screw driver while continuing to apply pressure on the brake piston tool. From what I have read they could retracted by turning either clockwise or counterclockwise.
Phenolic is a composite material and is used to reduce the transfer of heat from the brake pads to the brake fluid via the piston.
how do you release a parking brake for a 2006 sts cadillac
If it is the front brake use a "C" clamp to retract piston If it is the rear and the parking brake is used by this caliper piston is threaded and a special tool (not expensive) available at Sears or auto parts to "screw" piston into caliper body
You can adjust the brake pistons by adjusting the brake piston adjustment screw. Turn the screw to the right in order to back off the brake piston.
First the driver puts pressure in the foot brake, which then pushes a small piston, the piston then exerts pressure in the brake fluid. Then the increased pressure is transmitted through the fluid in the brake lines to a larger piston within the wheels of the car. Each piston pushes in a brake pad which the rubs against the brake disc, and the wheels motion is slowed down by the force of friction.
