The rear calipers on these models require a special tool that compresses and turns the piston in at the same time -- most parts stores carry this tool. It is called a caliper piston press -- and it installs where the pads would go and acts like a c-clamp,when turning handle it will turn the caliper piston backinto the caliper as it compresses it. Anytime the brake rotor or brake pads are being replaced, the rear caliper piston must be seated (bottomed) to compensate for the new brake rotor or lining. Because the Parking Brake self-adjuster mechanism is attached to the piston, a special seating method is required. The only acceptable method is by rotating the piston back into the bore using Retractor,MILLER Special Tool 8807, . Any other seating method will damage the self-adjuster mechanism. Good luck and hope this helps.
Just got done with a 2008 Doge Van back brakes. The piston turned clock ways to go in. Had to buy a tool to turn the piston in. The tool cost a little over 10 dollars. It was not fun.
You can't just push the piston back in...you will damage the parking brake mechanism, piston and inner seals....you have to rotate it counter clockwise while gently pushing. Sometimes remove the parking brake arm will help.You can't just push the piston back in...you will damage the parking brake mechanism, piston and inner seals....you have to rotate it counter clockwise while gently pushing.

Use a c clamp to push the piston back in so you can put the new pads on, turn it slow so that the break fluid goes back in the holder slowly.
