Vibe FWD L4-1.8L VIN 8 (2004)
Important: Brake rotor thickness variation greater than the specification can cause brake pulsation.
1. 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.
2. Measure the brake rotor LRO. Refer to Brake Rotor Assembled Lateral Runout (LRO) Measurement. See: Testing and Inspection/Component
Tests and General Diagnostics/Brake Rotor Assembled Lateral Runout (LRO) Measurement
3. 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. See: Brake Rotor Assembled Lateral Runout (LRO) Correction
Methods/Indexing
4. 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. See: Brake Rotor Assembled Lateral Runout (LRO)

J 45101-100 Conical Brake Rotor Washers
Adjustment Procedure
Important: Brake rotor thickness variation greater than the specification can cause brake pulsation.
1. Measure the brake rotor thickness variation. Refer to Brake Rotor Thickness Variation Measurement. See: Testing and Inspection/Component
Tests and General Diagnostics/Brake Rotor Thickness Variation Measurement
Important: Brake rotor assembled lateral runout (LRO) greater than the specification can cause brake pulsation.
2. Measure the brake rotor LRO. Refer to Brake Rotor Assembled Lateral Runout (LRO) Measurement. See: Testing and Inspection/Component
Tests and General Diagnostics/Brake Rotor Assembled Lateral Runout (LRO) Measurement
3. Remove the 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 any 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. Refer to Brake Rotor Thickness Measurement. See: Testing and Inspection/Component Tests and General
Diagnostics/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 specification, complete the following steps:
11.1. Use the correct lathe speed setting in order to apply a non-directional finish.
11.2. If the lathe has a non-directional finishing tool, use 120 grit aluminum oxide sandpaper in order to apply a non-directional finish.
