THICKNESS INSPECTION
Check thickness of the disc rotor using a micrometer. Replace disc
rotor if thickness is under the wear limit.
.
ADJUSTMENT
If the brake pad is ground or replaced, or if there is an abnormal feel to the braking force, follow the procedure
below and perform break-in work.
CAUTION:
• Because the brake effectiveness is reduced, pay sufficient attention to the vehicle speed.
• Perform checks on a safe road and be careful of the traffic conditions.
1. Drive on straight and flat roads.
2. Stop the vehicle by depressing the brake pedal to generate braking force that stops the vehicle in 3 to 5
seconds.
3. Cool the brakes.
4. Repeat steps 1 to 3 until the abnormal feel in braking force disappears.

BRAKE PAD
BRAKE PAD : Inspection and Adjustment
INFOID:0000000010123125
Brake pad wear inspection
Check the brake pad thickness from the inspection hole in the cylin-
der body. Use a scale to check it if necessary.
ADJUSTMENT
If the brake pad is ground or replaced, or if there is an abnormal feel to the braking force, follow the procedure
below and perform break-in work.
CAUTION:
• Because the brake effectiveness is reduced, pay sufficient attention to the vehicle speed.
• Perform checks on a safe road and be careful of the traffic conditions.
1. Drive on straight and flat roads.
2. Stop the vehicle by depressing the brake pedal to generate braking force that stops the vehicle in 3 to 5
seconds.
3. Cool the brakes.
4. Repeat steps 1 to 3 until the abnormal feel in braking force disappears.
DISC ROTOR
DISC ROTOR : Inspection and Adjustment
INFOID:0000000010123126
Visual inspection
Check surface of the disc rotor for uneven wear, cracks, and serious damage. Replace if necessary. Refer to
RAX-7, "Removal and Installation"
.
RUNOUT INSPECTION
1. Use the wheel nuts and fasten the disc rotor to the wheel hub assembly (minimum 2 positions).
2. Check axial end play of wheel hub assembly.
.
3. Check runout using a dial indicator [at 10 mm (0.39 in) from
outer edge of disc rotor].
4. If runout is outside the specified value, find the minimum runout
point by shifting mounting positions of the disc rotor and wheel
hub by one hole.
5. If runout is outside the specified value after performing the
above operation, refinish disc rotor using Tool.
CAUTION:
• Perform grinding of disc rotor if disc rotor thickness is 0.3 mm (0.012 in) or more above the wear
limit thickness.
• Replace disc rotor if disc rotor thickness is less than 0.3 mm (0.012 in) above the wear limit
thickness. Refer to
RAX-7, "Removal and Installation"
