Replacing Rear Brake Pads and Rotors - Continued
Step 5 of 9. Removing 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 of 9. Install New 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 of 9. Reset Rear Brake Caliper
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 of 9. Reinstall Rear Caliper Mount and Install 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 of 9. Remount 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 per manufacturer's specifications 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. Note: until brake pads are broken in during the first 30 miles or so, the operation
of the brakes maybe slightly impaired.

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. |
