BRAKE: REAR BRAKE: INSPECTION

INSPECTION

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





2. INSPECT PAD LINING THICKNESS
(a) Using a ruler, measure the pad lining thickness.
Standard thickness:
9.5 mm (0.374 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 disc brake pad kit.
HINT: Be sure to check wear of the rear disc after replacing the brake pad with a new one.

3. INSPECT REAR DISC BRAKE PAD SUPPORT PLATE
(a) Make sure that the pad support plates have sufficient rebound, that there is no deformation, cracks or wear, and that all rust and dirt are removed.
If necessary, replace the pad support plate.
(b) Install the pad support plate and brake pad onto the disc brake cylinder mounting. Make sure that they are securely installed onto the mounting.
If necessary, replace the pad support plate.





4. INSPECT DISC THICKNESS
(a) Using a micrometer, measure the disc thickness.
Standard thickness:
10.0 mm (0.394 in.)
Minimum thickness:
8.5 mm (0.335 in.)
If the disc thickness is less than the minimum, replace the rear disc.
5. INSPECT DISC RUNOUT
(a) Check the bearing play in the axial direction and check for the axle hub runout Rear Axle Hub.





(b) Using SST to hold the disc, tighten the disc with the hub nuts.
SST: 09330-00021
Torque: 103 Nm (1050 kgf-cm, 76 ft-lbf)
HINT: Use SST to hold the disc while tightening the nuts.





(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 to make the minimum runout. 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.
(d) Remove the hub nuts and rear disc.
