Yes. There is a special tool for it.

that depends if it is front or rear calipers
Unlike the front calipers, pistons in the rear usually have to be rotated to compress them.
No need to rotate the front caliper pistons as you compress the front calipers. That process is only for the rear calipers because of the parking brake mechanism.
Most likely you need a special tool to turn the pistons in while they are compressed. AutoZone offers this tool in the loan-a-tool program, part number 27111.
rear brake pistons are called actuated pistons. And the twist in and out. You will need a special tool to twist them back into the caliper. Unlike the Front Pistons which can be pushed back.
The calipers are threaded and screw out.
Caliper pistons should retract if calipers are in working order. Calipers need to be removed and rebuilt or replaced. A brake fluid flush is highly recommended.
simple. get yourself a wrench set and an actuator tool to push in the rear pistons on the calipers.
Depending on the make/model/year of vehicle, you may have to get a rear caliper tool. Some rear calipers need to be turned to retract them.
no. on the front brake calipers the pistons have to be pushed back into the calipers to make room for the new brake pads. on the rear brake calipers the pistons have to be SCREWED back into the calipers. there are notches on the inner edge of the piston rim. you can engage the notches with large needle nose pliers or a large flat washer. turn the piston clockwise as you face it to get it to go in.
If parking brake is attached to these calipers a special tool (not expensive) is required, because these pistons are threaded Tool available at Sears or auto parts store
Yes. If your question is regarding the operation of the calipers. They do operate in the same manner as the front calipers.
