J 45101-100 Conical Brake Rotor Washers
Caution: Refer to Brake Dust Caution.
Important:
*
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 assembled 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).
1. Ensure that the caliper and caliper bracket that are already being supported, are clear from contacting any rotating components, such as the brake
rotor.
2. Remove the J 45101-100 and the lug nuts that were installed during the assembled LRO measurement procedure and/or the indexing correction
procedure.
3. Inspect the mounting surface of the hub/axle flange and the brake rotor to ensure that there are no foreign particles or debris remaining.
4. Set up the lathe, following the manufacturer's instructions.
5. Refinish the brake rotor, following the brake lathe manufacturer's instructions.
6. After each successive cut, inspect the brake rotor thickness.
7. If at any time the brake rotor exceeds the minimum allowable thickness after refinish specification, the brake rotor must be replaced. After
replacing the rotor, proceed to step 10.
8. After refinishing the brake rotor, use the following procedure in order to obtain the desired non-directional finish:
1. Follow the brake lathe manufacturer's recommended speed setting for applying a non-directional finish.
2. Using moderate pressure, apply the non-directional finish:
*
If the lathe is equipped with a non-directional finishing tool, apply the finish with 120-grit aluminum oxide sandpaper.
*
If the lathe is not equipped with a non-directional finishing tool, apply the finish with a sanding block and 150-grit aluminum oxide
sandpaper.
3. After applying a non-directional finish, clean each friction surface of the brake rotor with denatured alcohol, or an equivalent approved
brake cleaner.
9. Remove the lathe from the vehicle.
10. Measure the assembled LRO of the brake rotor.
11. If the brake rotor assembled LRO measurement still exceeds the maximum allowable specification, refer to Brake Rotor Assembled Lateral
Runout Correction. See: Brake Rotor Assembled Lateral Runout Correction
12. If the brake rotor assembled LRO is within specification, install the brake caliper and depress the brake pedal several times to secure the rotor in
place before removing the J 45101-100 and the lug nuts.

Caution: Refer to Brake Dust Caution.
Important:
*
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 thickness variation MUST be checked BEFORE checking for assembled lateral runout (LRO). Thickness variation exceeding
the maximum acceptable level can cause brake pulsation.
1. Matchmark the position of the brake rotor to the wheel studs if this has not been done already.
Important: Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the
hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral runout (LRO) of the
brake rotor, which could lead to brake pulsation.
