Front Brake Inspection

Using a ruler, measure the pad lining thickness.

Standard thickness:

12.5 mm (0.492 in.)

Minimum thickness:

1.0 mm (0.039 in.)

HINT:

Be sure to check wear of the front disc after replacing the brake pad with a new one.

Using a micrometer, measure the disc thickness.

Standard thickness:

30.0 mm (1.181 in.)

Minimum thickness :

27.0 mm (1.063 in.)

Check the cylinder bore and piston for rust or scoring. If necessary, replace the disc brake cylinder assembly.

Tighten the disc with the 3 hub nuts.

HINT:

Use SST (09330-00021) to hold the disc during measurement.

SST

Torque:

103 N*m{1,050 kgf*cm, 76 ft.*lbf}

Using a dial indicator, measure the disc runout 10 mm inside (0.39 in.) the outer edge of the 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 so that the runout will become minimal. If the runout exceeds the maximum even when the installation positions are changed, check the bearing play in the axial direction and the axle hub runout (Click here) 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.

Remove the front disc.
