Note
|
•
|
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. Refer to
Brake Rotor Thickness Variation Measurement
.
|
•
|
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). Refer to
Brake Rotor Assembled Lateral Runout Measurement
.
|
Remove the
CH-45101-100
Conical Brake Rotor Washers and the lug nuts that were installed during the assembled LRO measurement procedure.
|
2.
|
Inspect the mating surface of the hub/axle flange and the brake rotor to ensure that there are no foreign particles or debris remaining.
|
3.
|
Index the brake rotor in a different orientation to the hub/axle flange.
|
4.
|
Hold the rotor firmly in place against the hub/axle flange and install one of th
CH-45101-100
conical brake rotor washers (1), and one lug nut (2) onto the upper-most wheel stud.
|
5.
|
Continue to hold the rotor secure and tighten the lug nut firmly by hand.
|
6.
|
Install the remaining
CH-45101-100
conical brake rotor washers and lug nuts onto the wheel studs and tighten the nuts firmly by hand in a star-pattern.
|
9.
|
Compare the amount of change between this measurement and the original measurement.
|
10.
|
If this measurement is within specifications, proceed to step 14.
|
11.
|
If this measurement still exceeds specifications, repeat steps 1-9 until the best assembled LRO measurement is obtained.
|
12.
|
Matchmark the final location of the rotor to the wheel studs if the orientation is different than it was originally.
|
14.
|
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
CH-45101-100
Conical Brake Rotor Washers and the lug nuts.
