Note:This procedure is not used in Europe.

Special Tools

CH-45101-100 Conical Brake Rotor Washers

For equivalent regional tools, refer toSpecial Tools.

Warning:Refer toBrake Dust Warning.

Note:

Brake rotor thickness variation MUST be checked BEFORE checking for assembled lateralrunout (LRO). Thickness variation exceeding the maximum acceptable level can causebrake pulsation. Refer toBrake Rotor Thickness Variation Measurement.Brake rotor assembled LRO exceeding the maximum allowable specification can causethickness variation to develop in the brake rotor over time, usually between 4 800–11300-km (3,000–7,000-mi). Refer toBrake Rotor Assembled Lateral Runout Measurement.Ensure that the caliper and caliper bracket that are already being supported, areclear from contacting any rotating components, such as the brake rotor.Remove the CH-45101-100 Conical Brake Rotor Washersand the lug nuts that were installed during the assembled LRO measurement procedureand/or the indexing correction procedure.Inspect the mounting surface of the hub/axle flange and the brake rotor to ensurethat there are no foreign particles or debris remaining.Set up the lathe, following the manufacturer's instructions.Refinish the brake rotor, following the brake lathe manufacturer's instructions.After each successive cut, inspect the brake rotor thickness. Refer toBrake Rotor Thickness Measurement.If at any time the brake rotor exceeds the minimum allowable thickness after refinishspecification, the brake rotor must be replaced. After replacing the rotor, proceedto step-10.After refinishing the brake rotor, use the following procedure in order to obtainthe desired non-directional finish:Follow the brake lathe manufacturer's recommended speed setting for applying a non-directionalfinish.Using moderate pressure, apply the non-directional finish:If the lathe is equipped with a non-directional finishing tool, apply the finish with120-grit aluminum oxide sandpaper.If the lathe is not equipped with a non-directional finishing tool, apply the finishwith a sanding block and 150-grit aluminum oxide sandpaper.After applying a non-directional finish, clean each friction surface of the brakerotor with denatured alcohol, or an equivalent approved brake cleaner.Remove the lathe from the vehicle.Measure the assembled LRO of the brake rotor. Refer toBrake Rotor Assembled Lateral Runout Measurement.If the brake rotor assembled LRO measurement still exceeds the maximum allowable specification,refer toBrake Rotor Assembled Lateral Runout Correction.If the brake rotor assembled LRO is within specification, install the brake caliperand depress the brake pedal several times to secure the rotor in place before removingthe CH-45101-100 Conical Brake Rotor Washersand the lug nuts.
