Brake Pads Inspection
Check the outer pads by looking at each caliper from
above. Check the thickness on the inner pad by looking
down through the inspection hole in the top of the caliper.
Whenever the pad is worn to about the thickness of the
pad base, the pad should be removed for further
measurements. The pad should be replaced anytime the
pad thickness (1) is worn to within 1.0 mm (0.039 in) of the
pad itself.
Wear indicators are installed on disc brake pads, disc
brake pads need replacement when the wear indicator is
heard.
