Brake Pad: Specifications

- Inspect the disc brake pads at least twice a year when the wheels are removed for rotation, etc..
- Inspect both ends of the outer pad by looking in at each end of the caliper. The highest rate of wear normally occurs at the ends.
- Inspect the thickness of the inner pad in order to ensure that it has not worn prematurely. Look through the window in the top of the caliper in order to view the inner pad.
- Both front and rear disc brakes have wear indicators that makes a noise when the pads wear below specifications. The wear indicator is an integral part of the outer pad. When the pad is worn, the wear indicator contacts the rotor (vented front:non-vented rear) and produces a warning noise as indicated in the illustration above.
- Replace the pads when the thickness is worn to within 0.76 mm (0.030 in) of the shoe. Replace all pads in axle sets.
- Measure the flatness of the inner and outer pads. Place the pad surfaces together and measure the gap between the surfaces. If more than 0.13 mph. (0.005 in) gap exists midway between the attaching lugs, replace the pads.
