Brake Rotor Replacement - Front

Brake Rotor Replacement - Front

Removal Procedure

Tools Required
J 42450-A Wheel Hub Cleaning Kit

Caution: Refer to Brake Dust Caution in Service Precautions.

1. Inspect the brake fluid level in the brake master cylinder reservoir,





2. If the brake fluid 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, using a appropriate tool, remove the brake fluid to the midway point before proceeding.
4. Raise the vehicle.
5. Remove the tire and wheel assembly.





6. Compress the front brake caliper piston.
6.1. Install a large C-clamp over the top of the brake caliper housing and against the back of the outboard brake pad.
6.2. Slowly tighten the C-clamp until the piston pushes into the brake caliper enough to slide the brake caliper off the rotor.
6.3. Remove the C-clamp from the brake caliper.





7. Remove the mounting bolts from the brake caliper mounting bracket.

Important: When performing the following service procedure, the front brake caliper assembly and the front brake caliper mounting bracket can be removed as an assembly.





8. Remove the brake caliper and mounting bracket assembly.





9. Remove the retaining clips from the brake rotor.

Notice: Whenever the brake rotor has been separated from the wheel bearing flange, clean any rust or foreign material from the mating surface of the rotor and flange with the J 42450 hub cleaning kit. Failure to do this may result in increased lateral runout of the rotor and brake pulsation.

Important: If the brake rotor is not going to be replaced but just removed from the front hub, mark the relationship of the brake rotor and a wheel stud.





10. Remove the front brake rotor from the wheel hub.





11. Using the J 42450-A, clean the brake rotor contact area on the front hub.

Installation Procedure

Important: Ensure that the relationship marks on the brake rotor and the wheel stud are aligned before installing the brake rotor.





1. Install the brake rotor to the wheel hub.





2. Install the brake caliper assembly to the steering knuckle.

Notice: Refer to Fastener Notice in Service Precautions.





3. Install the brake caliper mounting bolt.
^ Tighten the brake caliper bracket mounting bolt to 180 Nm (133 ft. lbs.).
4. Install the tire and wheel assembly.
5. Lower the vehicle.
6. Fill the brake master cylinder to the proper level.

Caution: Refer to Firm Brake Pedal Caution in Service Precautions.

7. Pump the brake pedal slowly and firmly in order to seat the brake pads.
8. Burnish the replaced or refinished rotors.
