INSPECT BRAKE CYLINDER AND PISTON

INSPECT REAR DISC THICKNESS

INSPECT PAD LINING THICKNESS

INSPECT DISC RUNOUT

Inspect the cylinder bore and the piston for rust or scoring.

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

Using a micrometer, measure the disc thickness.

• Standard thickness:
• 10.0 mm (0.390 in.)

• Minimum thickness:
• 8.5 mm (0.334 in.)

Using a ruler, measure the pad lining thickness.

• Standard thickness:
• 10.5 mm (0.413 in.)

• Minimum thickness:
• 1.0 mm (0.039 in.)

Temporarily fasten the rear disc with the hub nuts.

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

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

Remove the rear disc.
