4.
If the runout cannot be corrected by changing the position of the brake disc, replace the brake disc.
Rear Brake
Rear brake disc thickness check
1.
Check the brake pads for wear and fade.
2.
Check the brake disc for damage and cracks.
3.
Remove all rust and contamination from the surface, and measure the disc thickness at 8 points, at least, of same distance (5mm) from the brake disc outer circle.

Rear brake disc runout check
1.
Place a dial gauge about 5mm (0.2 in.) from the outer circumference of the brake disc, and measure the runout of the disc.
Brake disc runout
Limit: 0.03 mm (0.00118 in.) or less (new one)

2.
If the runout of the brake disc exceeds the limit specification, replace the disc, and then measure the runout again.
3.
If the runout exceeds the limit specification, install the brake disc after turning it 180° and then check the runout of the brake disc again.
4.
If the runout cannot be corrected by changing the position of the brake disc, replace the brake disc.
