Jack up the vehicle and support it with rigid racks. Remove the wheels.

Visually check the pad thickness through inspection hole of disc brake assembly. Replace the pad if necessary.

NOTE: When replacing a pad, always replace the pads for both the left and right wheels at the same time. Also replace the pad clips if they are twisted or worn.
