DISC INSPECTION





1. MEASURE DISC THICKNESS
Using a micrometer, measure the disc thickness.
Standard thickness: 28.0 mm (1.102 inch)
Minimum thickness: 26.0 mm (1.024 inch)
Replace the disc if the thickness of the disc is at the minimum or less. Replace the disc or grind it on a lathe if it is scored or worn unevenly.
2. MEASURE DISC RUNOUT





a. Tighten the disc with the 3 hub nuts.

HINT: Using SST 09330-00021 to hold the disc during measurement.

Torque: 103 Nm (1,050 kgf.cm, 76 ft. lbs.)





b. Using a dial indicator, measure the disc runout at a position 10 mm (0.39 inch) from the out side edge.
Maximum disc runout: 0.05 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, 2 screws and disc. Reinstall the disc 1/5 of a turn round from its original position on the hub. Install and torque the 3 hub nuts.
Remeasure the disc runout. Make a note of the runout and the disc's position on the hub.

HINT: Use SST 09330-00021 to hold the disc during loosening/torquing the hub nuts.

Torque: 103 Nm (1,050 kgf.cm, 76 ft. lbs.)
b. Repeat (a) until the disc has been installed on the 3 remaining hub position.
c. If the minimum runout recorded in (a) and (b) is less than 0.05 mm (0.0020 inch), install the disc in that position.
d. If the minimum runout recorded in (a) and (b) is greater than 0.05 mm (0.0020 inch), replace the disc and repeat step 2.
