FRONT BRAKE

INSPECTION
1. INSPECT BRAKE CYLINDER AND PISTON
(a) Check the brake cylinder bore and disc brake piston for rust or scoring.
If necessary, replace the disc brake cylinder assembly and disc brake piston.





2. INSPECT DISC BRAKE PAD KIT FRONT (PAD ONLY)
(a) Using a ruler, measure the pad lining thickness.
Standard thickness: 12.0 mm (0.472 in.)
Minimum thickness: 1.0 mm (0.039 in.)
If the pad lining thickness is equal to or less than the minimum thickness, replace the brake pad.

3. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE
(a) Inspect the pad support plate (No. 1).

HINT:
Make sure that both plates have sufficient rebound and have no deformation, cracks or wear, and that all rust and dirt is cleaned off.
If necessary, replace the brake pad support plates.

4. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE
(a) Inspect the pad support plate (No. 2).

HINT:
Make sure that both plates have sufficient rebound and have no deformation, cracks or wear, and that all rust and dirt is cleaned off.
If necessary, replace the brake pad support plates.





5. INSPECT BRAKE DISC
(a) Using a micrometer, measure the disc thickness.
Standard thickness: 28.0 mm (1.102 in.)
Minimum thickness: 26.0 mm (1.024 in.)
If the disc thickness is less than the minimum, replace the disc.





6. REMOVE FRONT DISC
(a) Put matchmarks on the front disc and the axle hub.
(b) Remove the front disc.

7. INSTALL FRONT DISC
(a) Aligning the matchmarks, install the front disc.

HINT: When replacing the disc with a new one, select the installation position where the front disc has the minimum runout.





8. INSPECT DISC RUNOUT
(a) Check the bearing play in the axial direction and check for axle hub runout.
(b) Temporarily fasten the front disc together with the hub nuts.
Torque: 103 N*m (1,050 kgf/cm, 76 ft. lbs.)
(c) Using a dial indicator, measure the disc runout 10 mm (0.39 in.) 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.
