    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. Use the J 42450-A  , or equivalent, in order to clean the mating surface of the hub flange (4). See Special Tools and Equipment .
  2. Use denatured alcohol, or an equivalent brake cleaner, in order to clean the hub.
  3. Use the J 41013  , or equivalent, in order to clean the mating surface of the brake rotor. See Special Tools and Equipment .
  4. Use denatured alcohol, or an equivalent brake cleaner, in order to clean the rotor.
  5. Inspect the mating surfaces of the hub and the rotor. Verify that there are no foreign particles or debris remaining.
  6. Install the brake rotor to the hub. If you are installing the old brake rotor, align the paint marks in order to install the brake rotor in the original position on the hub.
  7. If you removed and installed the old 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 (LRO) 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 (LRO) Correction .
  9. Install the brake caliper and the brake caliper bracket as an assembly to the suspension knuckle. Refer to Brake Caliper Bracket Replacement - Front .
  10. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
  11. Lower the vehicle.
  12. Press the brake pedal 3 times.
  13. Verify the brake fluid level is correct. Refer to Master Cylinder Reservoir Filling in Hydraulic Brakes.
  14. If you installed new pads or a new rotor, burnish the pads and rotors. Refer to Burnishing Pads and Rotors .
