Brake Rotor Surface and Wear Inspection
2. |
Clean the friction surfaces of
the brake rotor with denatured alcohol, or an equivalent approved
brake cleaner. |
3. |
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. Refer to
Brake Rotor Refinishing . |
|
• |
Cracks and/or heat
spots. |
|
• |
Excessive blueing
discoloration. |
5. |
Using an appropriate tool (1)
for measurement, calibrated in thousandths-of-a-millimeter, or
ten-thousandths-of-an-inch, measure and record the scoring depth of
any grooves present on the rotor friction surfaces. |
6. |
Compare the groove scoring
depth recorded disc brake component Specifications. |
