Caution: Refer to Brake Dust Caution in the Preface section.
- If the inboard friction surface of the brake rotor is not accessible,
reposition and support the caliper with the brake pads. Refer to
Front Disc Brake Pads Replacement
and/or
Rear Disc Brake Pads Replacement
, if equipped.
- Clean the friction surfaces of the brake rotor with denatured alcohol,
or an equivalent approved brake cleaner.
- Inspect the friction surfaces of the brake rotor for the following Braking
Surface Conditions:
| • | Heavy rust and/or pitting |
| • | Light surface rust can be removed with an abrasive disc. Heavy surface rust
and/or pitting must be removed by refinishing the rotor. |
| • | Cracks and/or heat spots |
| • | Excessive blueing discoloration |
- If the friction surfaces of the brake rotor exhibit one or more of the
Braking Surface Conditions, the rotor requires refinishing or replacement.
- Using a micrometer calibrated in thousanths-of-a-millimeter,
or ten-thousanths-of-an-inch, measure and record the scoring depth of any grooves
present on the rotor friction surfaces.
- Compare the groove scoring depth recorded to the following specification:
Specification
Brake rotor maximum allowable scoring: 1.50 mm (0.059 in)
- If the brake rotor scoring depth exceeds the specification, or if an
excessive amount of scoring is present, the rotor requires refinishing or replacement.
