Unlike the front calipers which can be compressed using a C clamp, the rear pistons must be turned as they are compressed. If you look at the surface of the piston you should see two notches. You should use a rear caliber pistol tool which could cost about $70 (search Google and you'll find several). I was in a hurry and did not have such a tool so I used was a pair of needle nose pliers. It's a crude solution but effective. Be mindful though...it takes a significant amount of force to compress and turn the piston at the same time. My advice would be to wear thick gloves. Also, be careful that the pliers don't slip off the piston head and tear the boot. Visit this website for more info http://www.audiworld.com/tech/wheel24.shtml
You need a tool that can compress the piston at the same time you can rotate the caliper clockwise. Or you can use a clamp and a screwdriver to gently compress the piston.
If you can't compress the piston with a C clamp back in to position to fit the new brake pads I would suggest replacing the caliper completely.
You twist it in. use a big screw driver or big flat object to screw it in counter clockwise. You will see a big slit in the piston to do this
Buy a small universal piston retractor from an auto supply shop (square in shape with strange different shapes coming out of it) find the correct side of the tool, the one that best fits the grooves on the piston. Attach the piston retractor tool to your ratchet Rotate the piston back into the caliper as you would with a bolt or screw.
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.

Usually you can take a block of wood and a C clamp and that usually works on any caliper, I have even taken the caliper completely off and used the handle of a hammer by putting the handle inside the caliper piston and applying downward force. However im having trouble compressing mine now.
you take a pair of plyers or a caliper kit from autozone and turn in the calipers. You have to turn them clockwise to make them go back in. do not try and compress them in, you will damage them.
There is a 14 mm bolt on back of caliper. Remove this & use a 4 mm Allen wrench to back piston into caliper.
They screw in. Unlike the front where you can press them in. There is a special tool that looks like a block and goes over the piston and sets in the groove on the piston. Screw in to press in piston. Be careful if you use pliers to screw inward. You can rip the rubber.
Yes
How do you compress the rear break caliper, pistons on a 2002 Sierra ?
