Information:
Front brake pads provide up to 70% of vehicle stopping power. In general, front brake pads wear out twice as fast as rear brake pads, 2 to1. Disc brakes have a definite braking power advantage over drum style brakes and performance is not compromised as much when wet. Some disc brakes utilize cooling fins in-between the braking surfaces to maximize cooling efficiency. Replacing brake discs can vary depending on the make and model of car or truck, two wheel or four wheel drive. Always replace brake rotors with top quality or OEM (original equipment manufacturer) brake rotors, some less expensive brake rotors can squeak and not dissipate heat as well because of there inferior metal quality. (Always wear protective safety goggles and gloves before work begins)

Removal:

– If shims are rusted or show peeling of the rubber coat, replace them with new shims.

– Whenever the brake pads are replaced, the inner shim, the outer shim and the shim cover have to be replaced as a set.

1. Remove master cylinder reservoir cap.

2. Locate caliper mounting bolts, apply wrench pressure counter clockwise to remove the bolt.

3. Suspend the cylinder body with wire. Then remove pads with retainers, inner and outer shims and pad return springs.

Installation

1. Attach the inner shim and shim cover to the inner pad and attach the outer shim to the outer pad.

2. Apply grease to the contact surface of pad retainer with the pads, then attach the pad retainer, pads and pad return spring to the torque member.

3. To install the new brake pads you must retract the brake caliper piston. Install C clamp tool and gently tighten clamp until caliper piston is fully depressed.

– Use old brake pad to protect the caliper piston.

– Do not compress the caliper piston with the other caliper removed.

4. Install the cylinder body to the torque member.

5. Insert a main pin bolt (on the lower side) and tighten it to specification.

6. Check the brakes for drag.
