Brake Rotor Assembled Lateral Runout Correction

NOTE:

Brake rotor thickness variation MUST be checked BEFORE checking for assembled lateral runout (LRO). Thickness variation exceeding the maximum acceptable level can cause brake pulsation. Brake Rotor Thickness Variation Measurement
Brake rotor assembled lateral runout (LRO) exceeding the maximum allowable specification can cause thickness variation to develop in the brake rotor over time, usually between 4, 800-11, 300 km (3, 000-7, 000 mi). Brake Rotor Assembled Lateral Runout Measurement

Review the following acceptable method for bringing the brake rotor assembled LRO to within specifications.

The indexing method of correcting assembled LRO is most effective when the LRO specification is only exceeded by a relatively small amount: 0.025-0.127 mm (0.001-0.005 in). Indexing is used to achieve the best possible match of high spots to low spots between related components. Brake Rotor Assembled Lateral Runout Correction - Indexing

If the assembled LRO cannot be corrected using this method, then other components must be suspected as causing and/or contributing to the LRO concern.
