Measuring Disc Thickness
-
Using a micrometer, measure disc thickness at eight points, approximately 45° apart and 10 mm (0.4 in) in from the outer edge of the disc.
Specs:
Brake Disc Parallelism 0.015 mm (0.0006 in)
NOTE: This is the maximum allowable difference between the thickness measurements.
Brake Disc Thickness
Standard 21.0 mm (0.83 in)
Max. Refinishing Limit 19.0 mm (0.75 in)
NOTE: Replace the brake disc if the smallest measurement is less than the max. refinishing limit.
-
If the disc is beyond the service limit for parallelism, refinish the brake disc with an on-car brake lathe.
NOTE: The "Kwik-Lathe" produced by Kwik-Way Manufacturing Co. and the "Front Brake Disc Lathe" offered by Snap-on Tools Co. are
approved for this operation.
