Rear Brake

BRAKE (REAR): REAR BRAKE: INSPECTION

1. INSPECT BRAKE CYLINDER AND PISTON

(a) Check the cylinder bore and piston for rust or scoring.

If necessary, replace the rear disc brake cylinder assembly and rear disc brake piston.

2. INSPECT PAD LINING THICKNESS

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

Standard thickness:

10.5 mm (0.413 in.)

Minimum thickness:

1.0 mm (0.0394 in.)

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

3. INSPECT DISC THICKNESS

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

Standard thickness:

18.0 mm (0.709 in.)

Minimum thickness:

16.5 mm (0.650 in.)

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

4. INSPECT DISC RUNOUT

(a) Using SST to hold the disc, tighten the 5 hub nuts.





SST : 09330-00021

Torque : 103 Nm (1050 kgf-cm, 76 ft-lbf)

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

Maximum disc runout:

0.05 mm (0.00197 in.)

NOTICE:
* Keep the magnet of the dial indicator away from the axle hub and speed sensor.
* Install the dial indicator to the shock absorber.

HINT
If the runout exceeds the maximum value, change the installation position of the disc on the rear axle hub to minimize the runout. If the runout exceeds the maximum even after the installation position is changed, check the bearing play in the axial direction and the axle hub runout Rear Axle Hub. If the bearing play 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.
