Replacing Rear Brake Pads and Rotors
(Always wear protective safety goggles and gloves before work begins)
Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.

Step 1 of 9. Identify Rear Disc Brake Components


Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 of 9. Removing The Rear Brake Caliper Mount Bolts


To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 of 9. Lift Rear Brake Caliper From The Caliper Mount


After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.
Step 4 of 9. Removing Caliper Mount Bolts


With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle.
Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.



Thats all! :naughty:

To return the piston back into the bore you need to remove the screw plug that covers the adjustment gear on the back of the caliper. Turn the adjustment gear counterclockwise with an allen wrench to put the piston in the back of the bore. After putting the pads on, turn the adjustment gear clockwise until the pads just contact the rotor. Back off the gear 1/3 turn, then install the screw plug.
