Disassembly Procedure
- Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
- Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
- Remove the caliper from the vehicle. Refer to Brake Caliper Replacement .
- Insert a block of hard wood or a shop cloth (2) into the caliper interior (1) to catch the piston as it is forced out of the bore with compressed air.
- Remove the piston from the caliper by applying compressed air to the caliper brake hose connector hole.
- Remove the rubber boot from the caliper groove.
- Use a flat plastic tool in order to remove the piston seal (1) from the caliper (2).
- Remove the bleeder valve from the caliper.
- Clean the following items in brake fluid:
- Inspect the piston for scoring, corrosion and any damage to the chrome plating. Replace the piston if any of these conditions exist.
- Inspect the caliper cylinder bore for scoring, pitting and corrosion. Use a crocus cloth to polish out any light corrosion. If the corrosion cannot be removed, replace the caliper.
Caution: Do not place your fingers in front of the piston in order to catch or protect the piston while applying compressed air. This could result in serious injury.
Caution: Wear safety glasses in order to avoid eye damage.
Notice: Use just enough air pressure to ease the piston out of the bore. You can damage a blown-out piston even with the padding.
Caution: Brake fluid may irritate eyes and skin. In case of contact, take the following actions:
| • | Eye contact--rinse thoroughly with water. |
| • | Skin contact--wash with soap and water. |
| • | If ingested--consult a physician immediately. |
Notice: Brake fluid will damage electrical connections and painted surfaces. Use shop cloths, suitable containers, and fender covers to prevent brake fluid from contacting these areas. Always re-seal and wipe off brake fluid containers to prevent spills.
| • | The caliper set ring |
| • | The piston |
| • | The caliper cylinder bore |
Assembly Procedure
- Install a new piston seal into the caliper bore.
- Install a new piston boot (2) onto the piston (1).
- Install the piston into the caliper (1).
- Fit the piston boot (3) onto the caliper groove.
- Pull on the piston in order to confirm that the boot is properly fitted in the caliper groove.
- Push the piston into the caliper. Seat the piston in the caliper bore.
- Install the bleeder valve. DO NOT tighten.
- Install the caliper on the vehicle. Refer to Brake Caliper Replacement .
- Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
- Lower the vehicle.
- Bleed the brake system. Refer to Hydraulic Brake System Bleeding in Hydraulic Brakes.
Important: Do not pull the piston out of the cylinder.
Important: Tighten the bleeder valve while bleeding the hydraulic brake system.
