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. 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 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. 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.
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.
6. 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
matchmark 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 the J 45101-100 (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.
