THICKNESS INSPECTION

Check thickness of the disc rotor using a micrometer. Replace disc

rotor if thickness is under the wear limit. 

FAX-9, "Removal and Instal-

lation"

.

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.

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

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. 

RAX-6, "Inspection"

.

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"

.
