Front Brake

BRAKE: FRONT BRAKE:

INSPECTION

1. INSPECT BRAKE CYLINDER AND PISTON
(a) Check the brake cylinder bore and front disc brake 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
12.0 mm (0.472 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 FRONT 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
28.0 mm (1.102 in.)
Minimum
26.0 mm (1.024 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 front disc together with the 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 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 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 front disc.
