Front Brake Rotor Replacement



Brake Rotor Replacement

Removal Procedure

Caution: Refer to Brake Dust Caution (Brake Dust Caution) .

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice (Vehicle Damage Warnings) .






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 thew maximum-full point and the minimum allowable level, using an appropriate tool, remove the brake fluid to the midway point before proceeding.






4. Remove the wheel hub/speed sensor assembly. Refer to Wheel Hub/Speed Sensor Replacement (Service and Repair) .

Important: In the following service procedure, support the wheel hub/brake rotor assembly with wood when working on the bench.

5. Using 2 pieces of wood, support the wheel hub/brake rotor assembly.






6. Remove the wheel hub/speed sensor to brake rotor bolts.






7. Separate the brake rotor from the wheel bearing/hub assembly.
8. Clean the surface between the wheel bearing/hub assembly and the brake rotor.

Installation Procedure

Important: Whenever the brake rotor has been separated from the hub/axle flange, any rust of contaminants should be cleaned from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled runout (LRO) of the brake rotor, which could lead to brake pulsation.

1. Clean all rust and contaminants from the mating surfaces of the hub and rotor.
2. Inspect the mating surfaces of the hub.axle flange and the rotor to ensure there are no foreign particles or debris remaining.






3. Position the wheel bearing/hub on the brake rotor.

Notice: Refer to Fastener Notice (Fastener Notice) .






Important: The following service procedure is to be performed on a flat surface and to ensure the brake rotor is securely attached to the hub assembly prior to the final torquing procedure. DO NOT use air tools of any type for this procedure.

4. Install the wheel bearing/hub mounting bolts.

Tighten
1. Tighten the mounting bolts in a criss-cross pattern to 20 N.m (15 lb ft).
2. Tighten again in a criss-cross pattern to 110 N.m (81 lb ft).






5. Install the wheel bearing/hub, brake rotor assembly in the steering knuckle. Refer to Wheel Hub/Speed Sensor Replacement (Service and Repair) .
6. Lower the vehicle.






7. Inspect the fluid level. Refer to Master Cylinder Reservoir Filling (Master Cylinder Reservoir Filling) .
8. Burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing (Brake Pad and Rotor Burnishing) .
