Brake Rotor Assembled Lateral RUNOUT (LRO) Correction - On-Vehicle Lathe

  1. Measure the brake rotor thickness variation. See BRAKE ROTOR THICKNESS VARIATION  .
  2. Measure the brake rotor lateral runout. See BRAKE ROTOR ASSEMBLED LATERAL RUNOUT (LRO) MEASUREMENT  .
  3. Remove the Conical Brake Rotor Washers (J-45101-100) and the wheel nuts.
  4. Remove the rotor from the hub.
  5. Inspect the mounting surface of the hub and the brake rotor. Verify the surfaces are clean.
  6. Verify the caliper is hanging in a position away from the rotating components, such as the rotor and the lathe.
  7. Follow the lathe manufacturer's instructions in order to install the lathe.
  8. Follow the lathe manufacturer's instructions in order to refinish the brake rotor.
  9. Measure the thickness of the rotor. See BRAKE ROTOR THICKNESS MEASUREMENT  .
  10. If the thickness is less than the specification, replace the brake rotor.
  11. If the thickness is greater than the specifications, complete the following steps:
    • Use the correct lathe speed setting in order to apply a non-directional finish.
    • If the lathe has a non-directional finishing tool, use 120 grit aluminum oxide sandpaper in order to apply a non-directional finish.
    • If the lathe does not have a non-directional finishing tool, use a sanding block and 150 grit aluminum oxide sandpaper in order to apply a non-directional finish.
  12. Remove the lathe from the vehicle.
  13. Clean both sides of the rotor with denatured alcohol, or an equivalent approved brake cleaner.
  14. Measure the brake rotor lateral runout. See BRAKE ROTOR ASSEMBLED LATERAL RUNOUT (LRO) MEASUREMENT  .
  15. If the brake rotor lateral runout is greater than the specification, see BRAKE ROTOR ASSEMBLED LATERAL RUNOUT (LRO) CORRECTION  .
  16. If the brake rotor lateral runout is less than the specification, install the brake caliper.
  17. Press the brake pedal several times in order to position the brake rotor.
  18. Remove the wheel nuts.
  19. Remove the Conical Brake Rotor Washers.
  20. Install the tire and wheel assemblies.
