Front Brake

BRAKE: FRONT BRAKE: INSPECTION

1. INSPECT BRAKE CYLINDER AND PISTON

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

If necessary, replace the disc brake cylinder and piston.

2. INSPECT PAD LINING THICKNESS





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

Standard thickness:

11.5 mm (0.453 in.)

Minimum thickness:

1.0 mm (0.039 in.)

If the pad lining thickness is equal to or less than the minimum thickness, replace the disc brake pad kit.

3. INSPECT DISC THICKNESS





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

Standard thickness:

28.0 mm (1.102 in.)

Minimum thickness:

26.0 mm (1.024 in.)

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

4. INSPECT DISC RUNOUT

(a) Check the bearing play in the axial direction and check for the axle hub runout Axle System.

(b) Provisionally fasten the front disc together with the hub nuts.





Torque : 112 Nm (1,137 kgf-cm, 82 ft-lbf)

(c) Using a dial indicator, measure the disc runout 10 mm (0.39 in.) away from the outer edge of the front disc.

Maximum disc runout:

0.05 mm (0.0020 in.)

If the runout exceeds the maximum value, change the installation positions of the disc and axle to make the minimum runout. If the runout exceeds the maximum even when the installation positions are changed, grind the disc. If the disc thickness is less than the minimum, replace the front disc.
