BRAKE DISC INSPECTION1. Measure disc thickness.
- Using a micrometer, measure the disc thickness.
Standard thickness: 12.0 mm (0.472 inch)
Minimum thickness: 10.5 mm (0.413 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 badly scored or worn unevenly.
2. Measure disc runout.
- Using a dial indicator, measure the disc runout at a position 10 mm (0.394 inch)away from the out side edge.
Maximum disc runout: 0.05 mm (0.0020 inch)
- If the disc's runout is maximum value or greater, check the bearing play in the axial direction and check the axle hub runout.
- If the bearing play and axle hub runout are not abnormal, adjust the disc runout or grind it on a "On-Car" brake lathe.
3. If necessary, adjust disc runout.
a. Remove the 3 hub nuts and disc. Turn the disc 1/5 and reinstall the disc. Install and torque the 3 hub nuts.
b. Remeasure the disc runout. Make a note of the runout and the disc's position on the hub.
Torque: 103 Nm (76 ft. lbs.)
c. Repeat b) until the disc has been installed on the 3 remaining hub positions.
d. If the minimum runout recorded in b) and c) is less than 0.05 mm (0.0020 inch), install the disc in that position.
e. If the minimum runout recorded in b) and c) is greater than 0.05 mm (0.0020 inch), replace the disc and repeat step 3.
