Brake Pad: Testing and Inspection

DISK BRAKE PADS, ROTORS

INSPECT FOR WEAR

BRAKE PAD CHECK









1.
CAUTION:
If there is a significant difference in thickness between the brake pads at right and left, check the sliding area and the run-out of the brake disc (Refer to Brake Disc Check).

Visually check the thickness of brake pad from the inspection hole of the caliper body.
Standard value: 10.0 mm (0.39 inch)
Limit: 2.0 mm (0.08 inch)
2. If the brake pad thickness is less than the limit value, replace the brake pad (Refer to Brake Pad Replacement).

BRAKE DISC THICKNESS CHECK

1. Remove contaminants or corrosion from the brake disc surface.





2. Use a micrometer to measure the brake disc thickness at minimum eight points which are 10 mm (0.39 inch) inward from its circumference.
Standard value:

26.0 mm (1.02 inches)[ Front]
10.0 mm (0.39 inch)[ Rear]
Limit:

24.4 mm (0.96 inch)[ Front]
8.4 mm (0.33 inch)[ Rear]
3. If the brake disc thickness is worn beyond the limit value at more than one point, replace the brake disc and check its run-out.

BRAKE DISC RUN-OUT CHECK AND CORRECTION





Place a dial gauge ca. 5 mm (0.2 inch) inward from the circumference of the brake disc to measure its run-out.
Limit:

0.06 mm (0.0024 inch)[ Front]
0.08 mm (0.0032 inch)[ Rear]
