Brake Pad: Service and Repair
BRAKE PAD CHECKCAUTION
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 disc.
1. 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.
