Brake Pad: Testing and Inspection

Check the outer pad 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 1.00 mm (0.039 inch) of the pad itself.
The disc pads have a wear indicator that makes a noise when the pad wears to where the replacement is required.
Minimum limit (1): 1.0 mm (0.039 inch)
