Front Brake Caliper Replacement J55

Caution: Refer to Brake Dust Caution in the Preface section.

Caution: Refer to Brake Fluid Irritant Caution in the Preface section.

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.

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 the vehicle and suitably support. Refer to Lifting and Jacking the Vehicle.
5. Mark the relationship of the wheel to the axle flange.
6. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation.



7. Install a large C-clamp over the body of the brake caliper with the C-clamp ends against the rear of the caliper body and against the outer brake pads.
8. Tighten the C-clamp until the caliper pistons are compressed into the caliper bores enough to allow the caliper to slide past the brake rotor.
9. Remove the C-clamp from the brake caliper.



10. Remove the brake hose to caliper bolt attaching the brake hose to the brake caliper.
11. Remove and discard the 2 copper brake hose gaskets. These gaskets may be stuck to the brake caliper and/or the brake hose end.
12. Plug the opening in the brake caliper and pipe to prevent fluid loss and contamination.



13. Remove the brake caliper pin bolts (1).
14. Remove the brake caliper.

1. If reusing the brake caliper pin bolts and retainers, clean the brake caliper pin bolts and retainers using denatured alcohol, or equivalent.
2. Dry the brake caliper pin bolts and retainers, using non-lubricated, filtered air.
3. Install the brake caliper over the brake pads and into the brake caliper bracket.
4. Apply a thin coat of high temperature silicone brake lubricant to the brake caliper pin bolts: do NOT apply lubricant to the brake pad hardware.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

5. Install the brake caliper pin bolts.

Tighten
Tighten the brake caliper pin bolts to 113 N·m (83 lb ft).

Important: Install NEW copper brake hose gaskets.

6. Assemble the brake hose bolt and the NEW copper brake hose gaskets to the brake hose.
7. Install the brake hose to caliper bolt to the brake caliper.

Tighten
Tighten the brake hose to caliper bolt to 45 N·m (33 lb ft).

8. Bleed the brake system. Refer to Hydraulic Brake System Bleeding.
9. With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
10. Slowly release the brake pedal.
11. Wait 15 seconds, then repeat steps 9-10 until a firm brake pedal apply is obtained; this will properly seat the brake caliper pistons and brake pads.
12. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation.
13. Lower vehicle.
