1. Measure disc thickness.
- Using a micrometer, measure the disc thickness.
Standard thickness: 32.0 mm (1.260 inch)
Minimum thickness: 30.0 mm (1.181 inch)
- Replace the disc if the thickness of the disc is at the minimum thickness or less. Replace the disc or grind it on a lathe if it is scored or is worn unevenly.
2. Measure disc runout.
- Using a dial indicator, measure the disc runout at a position 10 mm (0.39 inch) from the out side edge.
Maximum disc runout: 0.07 mm (0.0028 inch)
- If the bearing play and axle hub runout are not abnormal, replace the disc or grind it on an "On-Car brake lathe".
HINT: Before measuring the runout, confirm that the front bearing preload is within the specification.
3. If necessary, replace disc.
a. Remove the front axle hub.
b. Remove the disc from the axle hub.
c. Install a new disc and torque the 5 bolts.
Torque: 74 Nm (54 ft. lbs.)
d. Install the axle hub and adjust the front bearing preload.
