- REMOVE FRONT DISC BRAKE BLEEDER PLUG CAP
- REMOVE FRONT DISC BRAKE BLEEDER PLUG
- INSPECT BRAKE CYLINDER AND PISTON
Check the brake cylinder bore and front disc brake piston for rust or scoring.
If necessary, replace the brake cylinder and piston.
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 the minimum thickness or less, replace the brake pad.
Inspect pad lining thickness 19. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE
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.
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.
Inspect disc thickness 21. REMOVE FRONT DISC
Put matchmarks on the front disc and the axle hub.
Remove the front disc.
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.
Install front disc 23. INSPECT DISC RUNOUT
Check the bearing play in the axial direction and check for the axle hub runout .
Temporarily fasten the front disc together with the hub nuts.
Torque: 103 N·mUsing 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.
Inspect disc runout
