Replace Rear Brake Pads and Rotors
Remove Rear Brake Rotor 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, hold on using both hands and do not drop. Step 6 - Install New Brake Rotor
Replace Rear Brake Rotor Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw. Step 7 - Reset Rear Brake Caliper
Using a Rear Caliper Reset Tool Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool. Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
Reinstall Rear Caliper Mount with New Rear Brake Pads After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required. Step 9 - Remount Rear Brake Caliper
Reinstall Rear Brake Caliper Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes. Common Problems
- Brake pads wear down too far contacting the rotor making a grinding noise.
- Caliper slides lock up not letting the caliper move causing one brake pad to wear out and not the other.
- If inferior parts are used they will squeak, grumble and not last as long.
Rear Brake Parts
||Rear Brake Pad - Semi metallic brake pads are generally made copper, brass, and steel wool shavings held together in a resin. Ceramic pads are also available for high performance applications.|
||Rear Brake Caliper - Brake calipers provide the squeezing power to the brake pads when you press the brake pedal down. Whether using standard master cylinder or ABS braking systems, brake calipers apply the pressure from the pads to the rotors.|
||Rear Brake Rotor - A brake disc is the rotating part of the braking system that contacts the brake pads. Heat and energy are transferred from the brake disc to the pads while providing friction to stop the car. Cross drill brake discs help dissipate heat more efficiently under extreme driving conditions like long down grades or repeated hard accelerations and decelerations.|
|Brake Master Cylinder - The brake master cylinder supplies brake fluid pressure to the brake system.|
