Want this question answered?
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.
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.
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.
There is a 14 mm bolt on back of caliper. Remove this & use a 4 mm Allen wrench to back piston into caliper.
How do you get the brake piston to retreat back in caliper ?
You will need to push the caliper piston back as well as rotated when you are replacing your rear brake pads. The caliper will need to be turned clockwise.
C or G clamps.
Remove wheels Loosen 2 caliper mounting bolts and remove Remove Rotor (if peel off type) Resecure caliper Remove brake pads Need to get special tool to retract piston into caliper Do not retract using "C" clamp these pistons have to screw back into calpier (Clockwise) After piston retracted totally install new brake pads and reverse procedure to install DO NOT MOVE VEHICLE UNTIL BRAKE IS PUMPED TO RESET PADS TO CALIPER
They need to be wound back in, using a special tool, a G-clamp also work to push it back, with the rotating part on the caliper piston.
The rear brakes you need a 3/8 standard wrench to open two bolts retaining the caliper. The piston caliper requires a special tool to "wind " it or screw it back in order to install the new brake pads. DO NOT PRESS THE CALIPER PISTON BACK. You have to "screw" or rotate it.

on the caliper take out the bottom bolt, there are two bolts that the caliper slides on and only undo the bottom one. Then the caliper will swing up and allow access to the disc pads . You need to get a G-clamp and push the piston in the caliper back( or else it wont fit back down). put it back together and pump the brakes to set the brake piston b4 you drive or the first time you go to brake you wont have any.
the caliper needs a special tool. the piston does not push straight in. the spring needs to be released at the rear of the caliper. then using the special tool the piston twists back in to place
