Tools Required
J 45101-100 
 Conical Brake Rotor Washers
Adjustment Procedure
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 Measurement
 .
 
- Remove the 
J 45101-100 
and the wheel nuts.
 
- Remove the rotor from the hub.
 
- Inspect the mounting surface of the hub and the brake rotor. Verify the surfaces are clean.
 
- Verify the caliper is hanging in a position away from any rotating components, such as the rotor and the lathe.
 
- Follow the lathe manufacturer's instructions in order to install the lathe.
 
- Follow the lathe manufacturer's instructions in order to refinish the brake rotor.
 
- Measure the thickness of the rotor. Refer to 
Brake Rotor Thickness Measurement
 .
 
- If the thickness is less than the specification, replace the brake rotor.
 
- 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. | 
 
| 11.3.  | If the lathe does not have a non-directional finishing tool, use a sanding block and 150 grit aluminum oxide sandpaper in order to apply a non-directional finish. | 
 
- Remove the lathe from the vehicle.
 
- Clean both sides of the rotor with denatured alcohol, or an equivalent approved brake cleaner.
 
- Measure the brake rotor LRO. Refer to 
Brake Rotor Assembled Lateral Runout Measurement
 .
 
- If the brake rotor LRO is greater than the specification, refer to 
Brake Rotor Assembled Lateral Runout Correction
 .
 
- If the brake rotor LRO is less than the specification, install the brake caliper.
 
- Press the brake pedal several times in order to position the brake rotor.
 
- Remove the wheel nuts.
 
- Remove the 
J 45101-100 
 .
 
- Install the tire and wheel assemblies. Refer to 
Tire and Wheel Removal and Installation
.
