Adjustment Procedure

WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

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

Measure the brake rotor thickness variation. Refer to Brake Rotor Thickness Variation Measurement .

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

Measure the brake rotor LRO. Refer to Brake Rotor Assembled Lateral Runout (LRO) Measurement .
If the LRO exceeds the specification by less than 0.127 mm (0.005 in), index the rotor in order to reduce the LRO to the specification. Refer to Brake Rotor Assembled Lateral Runout (LRO) Correction - Indexing .
If the LRO exceeds the specification by more than 0.127 mm (0.005 in), use an on-vehicle lathe in order to reduce the LRO to the specification. Refer to Brake Rotor Assembled Lateral Runout (LRO) Correction - On-Vehicle Lathe .
