For 1990-2009 cars only
Inspect the brake pads at regular intervals, and any time the wheels are removed (tire rotation, etc.) The outer pad has a wear sensor which makes noise when the pads wear to the point of requiring pad replacement.
When any brake pad thickness is worn to within 0.76 mm (1/32 in) of the pads or rivet, replace the pads in axle sets.
| • | Check both ends of the outer pads (1,3) by looking in at each end of the caliper. These points are where the highest rate of wear normally occurs. |
| • | Check the inner pad lining to make sure that it has not worn prematurely. |
| • | Look down through the hole in the top of the caliper to view the inner pad. Some inboard pads have a thermal layer against the pad, integrally molded with the lining. Do not confuse this extra layer with uneven inboard-outboard lining wear. |
