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 runout of the brake disk (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 DISK THICKNESS CHECK





1. Using a micrometer, measure disk thickness at eight positions, approximately 45 degrees apart and 10 mm (0.4 inch) in from the outer edge of the disk.
Standard value:

26.0 mm (1.02 inch) [Front]

10.0 mm (0.39 inch) [Rear]
Limit:

24.4 mm (0.96 inch) [Front]

8.4 mm (0.33 inch) [Rear]
NOTE:
Thickness variation (at least 8 positions) should not be more than 0.015 mm (0.0006 inch).

FRONT BRAKE DISK RUN-OUT CHECK AND CORRECTION





Place a dial gauge approximately 5 mm (0.2 inch) from the outer circumference of the brake disk, and measure the run-out of the disk.
Limit:

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