Brake Rotor Thickness Measurement
2. |
Clean the friction surfaces of
the brake rotor with denatured alcohol, or an equivalent approved
brake cleaner. |
3. |
Using a micrometer (1)
calibrated in thousandths-of-a-millimeter, or
ten-thousandths-of-an-inch, measure and record the lowest thickness
of the brake rotor at 4 or more points, equally spaced around the
rotor. |
|
Ensure that the measurements are only taken within the friction
surfaces and that the micrometer is positioned the same distance
from the outside edge of the rotor, about 13 mm (0.5
in) , for each measurement. |
4. |
Compare the lowest thickness
measurement to the disc brake component specifications.
|
5. |
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. |
6. |
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. |
