WARNING
!
Refer to "Brake Dust Caution: ".
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: ".
1. Remove the J 45101-100 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 J 45101-100 (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 J 45101-100 and lug nuts onto
the wheel studs and tighten the nuts firmly by hand
in a star-pattern.
7. Using the J 39544-KIT, or equivalent, tighten the lug
nuts in a star-pattern to specification, in order to
properly secure the rotor. Refer to "Tire and Wheel
Removal and Installation: ".
8. Measure the assembled LRO of the brake rotor.
Refer to "Brake Rotor Assembled Lateral Runout
Measurement: ".
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.
13. If the brake rotor assembled LRO measurement still
exceeds the maximum allowable specification, refer
to "Brake Rotor Assembled Lateral Runout
Correction: ".
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 J 45101-100 and the lug
nuts.
