Brake Caliper Replacement
Brake Caliper ReplacementCaution: Refer to Brake Fluid Irritant Caution in Service Precautions.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in Service Precautions.
Removal Procedure
1. Inspect the fluid level in the brake master cylinder reservoir.
2. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding.
3. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
4. Raise and support the vehicle. Refer to Vehicle Lifting.
5. Remove the tire and wheel assembly.
6. install and firmly hand tighten 2 wheel nuts to opposite wheel studs in order to retain the rotor to the hub.
7. Install a large C-clamp (1) over the body of the brake caliper (2) with the C-clamp ends against the rear of the caliper body and against the outer brake pad.
8. Tighten the C-clamp until the caliper piston is compressed into the caliper bore enough to allow the caliper to slide past the brake rotor.
9. Remove the C-clamp from the caliper.
10. Clean all dirt and foreign material from the brake hose end.
11. Remove the brake hose-to-caliper bolt (1) from the brake caliper.
12. Remove the brake hose (3) from the brake caliper.
13. Remove and discard the 2 copper brake hose gaskets (2). These gaskets may be stuck to the brake caliper and/or the brake hose end (3).
14. Cap or plug the opening in the brake caliper and the brake hose (3) to prevent fluid loss and contamination.
15. Fully loosen the caliper bolts from the steering knuckle.
16. Remove the brake caliper from the steering knuckle.
17. Remove the brake pads from the caliper.
18. Remove the disc brake caliper bolts (1) from the caliper assembly (3).
19. Inspect the caliper bolts (1) for rust, corrosion and/or damage.
20. If the bolts are rusty, corroded, and/or damaged, replace the bolts (1) and replace the bushings (2).
Installation Procedure
1. Lubricate the caliper bushings and install the caliper bolts to the caliper.
Important: The outer brake pad must be mounted with the leading edge of the wear sensor facing the brake rotor during forward wheel rotation, or at the top of the pad when installed in vehicle position.
2. Install the brake pads to the caliper.
3. Thoroughly clean the brake pad mating surface on the steering knuckle of any surface debris and/or corrosion.
4. Apply a thin layer of high temperature silicone brake lubricant to the brake pad mating surface on the steering knuckle.
5. Install the caliper assembly to the steering knuckle.
Notice: Refer to Fastener Notice in Service Precautions.
6. Tighten the caliper bolts to the steering knuckle.
^ Tighten the bolts to 51 Nm (38 lb ft).
7. Remove the caps or plugs from the opening in the brake caliper and the brake hose.
Important: Install NEW copper brake hose gaskets (2).
8. Assemble the NEW copper brake hose gaskets (2), and the brake hose bolt (1), to the brake hose (3).
Notice: Refer to Fastener Notice in Service Precautions.
9. Install the brake hose-to-brake caliper bolt to the brake caliper.
^ Tighten the bolt to 50 Nm (37 lb ft).
10. Bleed the hydraulic brake system.
11. Remove the wheel nuts securing the rotor to the hub.
12. Install the tire and wheel assembly.
13. Lower the vehicle.
14. With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
15. Slowly release the brake pedal.
16. Wait 15 seconds, then gradually apply the brake pedal approximately 2/3 of its travel distance again until a firm brake pedal apply is obtained. This will properly seat the brake caliper pistons and brake pads.
