CAUTION:

Whenever a pad must be replaced, replace both LH and RH wheel pads as a set to prevent the vehicle from pulling to one side when braking.
If there is a significant difference in the thicknesses of the pads on the left and right sides, check the sliding condition of the piston and slide pins.

Check the brake pad thickness through the caliper body check port.
Standard value: 10.0 mm (0.39 inch)

Minimum limit: 2.0mm (0.08 inch)
