Front Brake (for 6-Pot Caliper)

BRAKE: FRONT BRAKE (for 6-Pot Caliper): INSPECTION

1. INSPECT PAD LINING THICKNESS

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





Standard thickness:

9.75 mm (0.384 in.)

Minimum thickness:

1.0 mm (0.0394 in)

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

NOTICE:
Be sure to inspect the front disc when replacing the brake pads with new ones.

2. INSPECT FRONT DISC BRAKE ANTI-RATTLE SPRING

(a) Make sure that the front disc brake anti-rattle spring has sufficient rebound, no deformation, no cracks or wear, and that all rust and dirt are cleaned off. If necessary, replace the front disc brake anti-rattle spring.

3. INSPECT DISC THICKNESS

(a) Using a micrometer, measure the disc thickness as shown in the illustration.





Standard thickness:

36.0 mm (1.42 in.)

Minimum thickness:

33.0 mm (1.30 in.)

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

4. INSPECT DISC RUNOUT

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

Torque : 140 Nm (1428 kgf-cm, 106 ft-lbf)

(b) Using a dial indicator, measure the disc runout 10 mm (0.349 in.) away from the outer edge of the front disc.





Maximum disc runout:

0.04 mm (0.00157 in.)

(c) 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 Front Axle Hub and axle hub runout Front 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.

(d) Remove the front disc.
