1.

Refer to

|
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
.
|
Rotate the brake rotor to position the high spot, identified and marked during the brake rotor assembled LRO measurement procedure, to face upward.
|
|
2.
|
Remove the
CH-45101-100
Conical Brake Rotor Washers 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.
|
Select the correction plate, following the manufacturer's instructions, which has a specification closest to the assembled LRO measurement.
For example: If the assembled LRO measurement was 0.076 mm (0.003 in), the 0.076 mm (0.003 in) correction plate would be used. If the measurement was 0.127 mm (0.005 in), the 0.152 mm (0.006 in) correction plate would be used.
|
|
5.
|
Determine the positioning for the correction plate (1) using the high spot mark (3) made during the brake rotor assembled LRO measurement procedure.
|
|
6.
|
|
Note
|
|
•
|
Do NOT install used correction plates in an attempt to correct brake rotor assembled LRO.
|
|
•
|
Do NOT stack up, or install more than one correction plate onto one hub/axle flange location, in an attempt to correct brake rotor assembled LRO.
|
Install the correction plate (1) onto the hub/axle flange, with the V-shaped notch (2) orientated to align with the high spot mark (3), that was positioned to face upward.
|
|
7.
|
Install the brake rotor to the hub/axle flange. Use the match mark made prior to removal for proper orientation to the flange.
|
|
8.
|
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.
|
|
9.
|
Continue to hold the rotor secure and tighten the lug nut firmly by hand.
|
|
10.
|
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.
|
|
14.
|
If the brake rotor assembled LRO measurement 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.
