Rear Disc Brake

BRAKE: REAR DISC BRAKE:

INSPECTION

1. INSPECT BRAKE CYLINDER AND PISTON
(a) Check the cylinder bore and piston for rust or scoring.
If necessary, replace the brake cylinder and piston.
2. INSPECT PAD LINING THICKNESS





(a) Using a ruler, measure the pad lining thickness.
Thickness:
Standard
10.0 mm (0.394 in.)
Minimum
1.0 mm (0.039 in.)
If the pad lining thickness is equal to the minimum thickness or less, replace the brake pad.
3. INSPECT REAR DISC BRAKE PAD SUPPORT PLATE
(a) Inspect the front disc brake pad support plate No.1 and front disc brake pad support plate No.2.

HINT: Make sure that both have sufficient rebound, have no deformation, cracks or wear, and that all rust and dirt is cleaned off.

If necessary, replace the brake pad support plate.
4. INSPECT DISC THICKNESS





(a) Using a micrometer, measure the disc thickness.
Thickness:
Standard
12.0 mm (0.472 in.)
Minimum
10.5 mm (0.413 in.)
If the disc thickness is less than the minimum, replace the disc.
5. INSPECT DISC RUNOUT
(a) Check the bearing play in the axial direction and check for the axle hub runout (Axle System).
(b) Temporarily fasten the rear disc with hub nuts.
Torque: 103 Nm (1,050 kgf-cm, 76 ft-lbf)





(c) 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:
0.15 mm (0.0059 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, grind the disc. If the disc thickness is less than the minimum, replace the rear disc.
