Brake Rotor Assembled Lateral RUNOUT (LRO) Correction - Indexing
- Measure the brake rotor thickness variation. See BRAKE ROTOR THICKNESS VARIATION
.
- Measure the brake rotor lateral runout. See BRAKE ROTOR ASSEMBLED LATERAL RUNOUT (LRO) MEASUREMENT
.
- Remove the Conical Brake Rotor Washers (J-45101-100) and the wheel nuts.
- Remove the rotor from the hub.
- Rotate the rotor one wheel stud position.
- Install the rotor to the hub.
- Hold the rotor firmly against the hub. Install one of the Conical Brake Rotor Washers and one wheel nut on the top wheel stud.
- Continue to hold the rotor and tighten the wheel nut by hand.
- Install the remaining Conical Brake Rotor Washers and the wheel nuts.
- Tighten the wheel nuts firmly by hand in a star pattern.
- Tighten the wheel nuts in a star pattern in order to retain the rotor to the hub.
- Measure the brake rotor lateral runout. See BRAKE ROTOR ASSEMBLED LATERAL RUNOUT (LRO) MEASUREMENT
.
- If the brake rotor lateral runout is greater than the specifications, repeat this procedure with the rotor at the remaining 3 wheel stud positions.
- If the brake rotor lateral runout is greater than the specification at all 5 wheel stud position, use an on-vehicle lather in order to reduce the brake rotor lateral runout specification. See BRAKE ROTOR ASSEMBLED LATERAL RUNOUT (LRO) CORRECTION - ON-VEHICLE LATHE
.
- If the brake rotor lateral runout is less than the specification, complete the following steps:
- Use paint in order to mark the position of the brake rotor on the hub.
- Install the brake caliper.
- Press the brake pedal several times in order to position the brake rotor.
- Remove the wheel nuts.
- Remove the Conical Brake Rotor Washers.
- Install the tire and wheel assemblies.
