Chevrolet Sonic Repair Manual: Brake Rotor Thickness Measurement
Warning:
Refer to Brake Dust Warning.
- 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.
- Clean the friction surfaces of the brake rotor with denatured alcohol, or
an equivalent approved brake cleaner.
- Using a micrometer (1) calibrated in thousandths-of-a-millimeter, or ten-thousandths-of-an-inch,
measure and record the thickness of the brake rotor at four or more points,
evenly spaced around the brake rotor.
Make sure that the measurements are only taken within the friction surfaces
and that the micrometer is positioned the same distance from the outer edge
of the brake rotor, about 13 mm (1/2 in), for each measurement.
- Compare the lowest thickness measurement recorded to the specifications.
Refer to Disc Brake Component Specifications.
- If the lowest thickness measurement of the brake rotor is above the minimum
allowable thickness after refinishing specification, the brake 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
discard thickness specification, the brake rotor requires replacement.
