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.
You remove the caliper only to replace pads, and then caliper mounting bracket to replace rotor.
Remove wheels then push back the pistons then remove calipers and brackets then the rotors.
Remove wheels Remove 2 caliper mounting bolts Slide caliper off rotor Rotor will slide off hub Use a "C" clamp to fully retract pistons into caliper body Replace pads inner and outer Install rotor Slide caliper onto rotor and secure PUMP BRAKE PEDAL TO SET PADS AGAINST ROTOR PRIOR TO MOVING VEHICLE
I just changed my rotors and pads all the way around. The front pistons compress (used a C-clamp). The rear pistons screw clockwise back into the caliper. Good luck, I hope this helped. Rob in Idaho

Unlike the front calipers, pistons in the rear usually have to be rotated to compress them.
Take of the wheels 19mm take of the bolts holding the caliper on 18mm take of the bolts holding the caliper frame of 17mm remove all clips and pads install new pads in reverse order, install all clips and lube the sliding parts push caliper pistons back into calipers with cclamp or big pliers install new or turned rotors reinstall everything drive on
I just did mine. Use a screw driver to press the brake pads away from the rotor and compress the caliper pistons back some so you can remove the caliper off of hte rotor. Losen and remove the bolts to the brake caliper. DO NOT DISCONNECT the brake line from the caliper! Get you a c-clamp and a piece of 1/4 board about 4 inches long. Once you have removed the caliper from the mount and removed the brake pads support the caliper with one hand. Place the wood over the caliper pistons and using the c-clamp place it over the wood and center of both pistons and other side of caliper to compress the pistons back into the caliper. Make sure you DO NOT PINCH the rubber boots on the pistons. Once you have compressed the pistons back into the calipers install your new pads and calipers back on the mounting surface and tighten the bolts back to torque specs.
To change the brake rotors on a 1991 Honda Civic raise the vehicle. Remove the wheels and brake caliper bracket. Remove the brake pads. Loosen the rotor mounting screws and replace the rotors.
see the answer for removing rotors. stop before removing the caliper carrier. very simple.
Jack up and block the car remove wheel pry back the caliper pistons with out breaking the pistons then remove caliper and pads.Reverse to install and pump brake pedal until it gets hard.
When rotors need to be changed usually the pads have worn down. It is always a good idea to change pads when changing rotors.
