Warning: Refer to
Brake Dust Warning .
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 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 and 11,300 km (3,000 - 7,000
mi) . Refer to
Brake Rotor Assembled Lateral Runout Measurement . |
1. |
Remove the CH
45101-100 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 the CH
45101-100 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 washers (1) 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 calliper and depress
the brake pedal several times to secure the rotor in place before
removing the CH-45101-100 washers and the lug
nuts. |
