Lateral Runout (LRO) - Correction

Brake Rotor Assembled Lateral Runout (LRO) Correction

Adjustment Procedure

Important: Brake rotor thickness variation greater than the specification can cause brake pulsation.







1. Measure the brake rotor thickness variation.

Important: Brake rotor assembled lateral runout (LRO) greater than the specification can cause brake pulsation.

2. Measure the brake rotor LRO.

3. If the LRO exceeds the specification by less than 0.127 mm (0.005 inch), index the rotor in order to reduce the LRO to the specification.

4. If the LRO exceeds the specification by more than 0.127 mm (0.005 inch), use an on-vehicle lathe in order to reduce the LRO to the specification.
