Tools Required

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the front tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.




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.

Important: Do NOT disconnect the hydraulic brake flexible hose from the caliper.

3. Remove the brake caliper and the pads as an assembly and support the assembly with heavy mechanic's wire (2), or equivalent. Verify that there is no tension on the brake hose (3). Refer to Front Brake Caliper Replacement .




Important: The brake rotor is indexed to the hub during production in order to minimize assembled lateral runout (LRO).

4. If match marks are not evident, use paint in order to mark the relative position of the following components:

•	The brake rotor (1)

•	A wheel stud (2)

•	The hub (3)

5. Remove the brake rotor. If the brake rotor does not slide off of the hub easily, complete the following steps as necessary:

5.1.	Select a block of wood longer than the wheel studs.

5.2.	Place the wood on the rotor between the wheel studs.

5.3.	Tap the wood with a hammer in order to loosen the rotor from the hub.

Important: Clean the hub and the brake rotor mating surfaces. Failure to remove corrosion and other contaminants from the hub and the rotor may result in excessive assembled lateral runout (LRO) of the brake rotor, which could lead to brake pulsation.

1. Using the J 42450-A , thoroughly clean any corrosion from the mating surface of the hub flange.
2. Using the J 41013 , thoroughly clean any corrosion from the mating surface of the brake rotor.
3. Inspect the mating surfaces of the hub and the rotor. Verify that there are no foreign particles or debris remaining.
4. Using the J 41013 , thoroughly clean any corrosion from the mating surface of the brake caliper bracket and the knuckle.
5. Inspect the mating surfaces of the caliper bracket and the knuckle. Verify that there are no foreign particles or debris remaining.



6. Install the brake rotor to the hub. If you are installing the old rotor, align the match marks on the following components:

•	The brake rotor (1)

•	A wheel stud (2)

•	The hub (3)

7. If you removed and installed the brake rotor as part of a brake system repair, measure the assembled lateral runout (LRO) of the brake rotor in order to ensure optimum performance of the disc brakes. Refer to Brake Rotor Assembled Lateral Runout Measurement .
8. If the brake rotor assembled LRO measurement exceeds the specification, adjust the LRO to the specification. Refer to Brake Rotor Assembled Lateral Runout Correction .
9. Clean the brake rotor with denatured alcohol or an equivalent brake cleaner.
10. Install the brake caliper and the pads as an assembly. Refer to Front Brake Caliper Replacement .
11. Install the front tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
12. Lower the vehicle.
13. If you installed new pads or a new rotor, burnish the pads and rotors. Refer to Brake Pad and Rotor Burnishing .
