For 1990-2009 cars only
- Clean the brake pad lining contact surface of the brake rotor with denatured alcohol or an equivalent brake cleaner.
- Using a calibrated micrometer measure and record the lowest thickness of the brake rotor at 4 or more points equally spaced around the rotor.
- Compare the lowest thickness measurement recorded to the following specifications:
- If the lowest thickness measurement of the brake rotor is above the minimum allowable thickness after refinishing specification; the rotor may be able to be refinished, depending upon surface and wear conditions which may be present.
- If the lowest thickness measurement of the brake rotor is at or below the minimum allowable thickness after refinishing specification; the rotor may not be refinished.
- If the lowest thickness measurement of the brake rotor is at or below the discard thickness specification the rotor requires replacement.
Ensure that the measurements are only taken within the brake pad lining contact area and that the micrometer is positioned the same distance from the outside edge of the rotor for each measurement.
Specification -- Front Brake JF9
| • | Brake rotor minimum allowable thickness after refinishing 35.1 mm (1.382 in) |
| • | Brake rotor discard thickness 34.7 mm (1.366 in) |
