Rear Brake

BRAKE: REAR BRAKE: INSPECTION

1. CHECK BRAKE CYLINDER AND PISTON

(a) Check the cylinder bore and piston for rust or scoring. If necessary, replace the rear disc brake caliper assembly and piston.

2. CHECK PAD LINING THICKNESS

(a) Using a ruler, measure the pad lining thickness.





Standard thickness:

13.5 mm (0.532 in.)

Minimum thickness:

1.0 mm (0.0394 in.)

If the pad lining thickness is less than the minimum, replace the pad.

3. CHECK REAR DISC BRAKE ANTI-RATTLE SPRING

(a) Use brake cleaner to clean the rear disc brake anti-rattle spring. Check for deformation and cracks.

(b) When installing the rear disc brake anti-rattle spring to the rear disc brake caliper, check that the spring's force is applied to the hole pin and brake pad.

4. CHECK REAR DISC THICKNESS

(a) Using a micrometer, measure the disc thickness.





Standard thickness:

12.40 inch disc
20.0 mm (0.787 in.)

13.19 inch disc
22.0 mm (0.866 in.)

Minimum thickness:

12.40 inch disc
18.0 mm (0.709 in.)

13.19 inch disc
20.0 mm (0.787 in.)

If the disc thickness is less than the minimum, replace the rear disc.

5. CHECK DISC RUNOUT

(a) Fix the disc in place with the 5 hub nuts.

Torque : 140 Nm (1428 kgf-cm, 103 ft-lbf)

(b) Using a dial indicator, measure the disc runout 10 mm (0.394 in.) from the outer edge of the rear disc.





Maximum disc runout:

0.04 mm (0.00157 in.)

If the runout exceeds the maximum value, change the installation positions of the disc and axle so that the runout will become minimal. If the runout exceeds the maximum even when the installation positions are changed, check the bearing looseness in the axial direction Testing and Inspection and the axle hub runout Testing and Inspection. If the bearing looseness and the axle hub runout are normal, and if the disc thickness is not within the specified range, grind the disc. If the disc thickness is less than the minimum, replace the disc.

(c) Remove the 5 hub nuts and rear disc.
