Measuring Disc Thickness
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 Disc's thickness is at the minimum thickness or less. Replace the Disc or grind it on a lathe if it is badly scored or worn
unevenly.
Measuring Disc Runout
DISC RUNOUT
Using a dial indicator, measure Disc runout 10 mm (0.39 inch) from the outer edge of the Disc.
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.
