Front Brake Rotor Replacement

Front Brake Rotor Replacement


Tools Required
* J 41013 Rotor Resurfacing Kit
* J 42450-A Wheel Hub Resurfacing Kit



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

Notice: Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.


1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle (Service and Repair) .
2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (Service and Repair) .




3. Remove the brake caliper bracket bolts (1).
4. Without disconnecting the brake caliper hose, remove the brake caliper and bracket assembly and support with heavy mechanics wire or equivalent.
5. If installing the original brake rotor, mark the relationship of the rotor to the wheel hub.




6. Remove the brake rotor screw (1) and the brake rotor.
7. If the brake rotor is to be machined, check the thickness variation measurement. Refer to Brake Rotor Thickness Variation Measurement (Brake Rotor Thickness Variation Measurement) .



Installation Procedure

1. If installing a new brake rotor, clean the friction surfaces of the brake rotor with denatured alcohol.
2. Using the J 42450-A , thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
3. Using the J 41013 , thoroughly clean any rust or corrosion from the mating surface of the rotor to the hub/axle flange.

Notice: Refer to Fastener Notice (Fastener Notice) .





4. Install the brake rotor.
If installing the original brake rotor, align the rotor to the wheel hub as noted during removal.
5. Install the brake rotor screw (1).

Tighten the screw to 10 N.m (89 lb in).

6. After installing the brake rotor, measure the assembled lateral runout (LRO) of the brake rotor. Refer to Brake Rotor Assembled Lateral Runout Measurement (Brake Rotor Assembled Lateral Runout Measurement) .
7. If the brake rotor assembled LRO measurement exceeds specification, bring the LRO to within specification. Refer to Brake Rotor Assembled Lateral Runout Correction (Service and Repair) .




8. Position the brake caliper and bracket assembly to the vehicle.
9. Install the brake caliper bracket bolts (1).

Tighten the bolts to 185 N.m (136 lb ft).

10. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (Service and Repair) .
11. Lower the vehicle.
