1. Thickness and Parallelism Raise the front of the vehicle, and support it with safety stands in the proper locations. Remove the front wheels. Remove the brake pads. Using a micrometer, measure the brake disc thickness at eight points, about 45 ° apart and 10 mm (0.39 in.) in from the outer edge of the brake disc. Replace the brake disc if the smallest measurement is less than the max. refinishing limit.
   Brake disc thickness:
   | Standard:
   | Except KQ model:
   | 24.9−25.1 mm (0.98−0.99 in.)
   | KQ model:
   | 27.9−28.1 mm (1.10−1.11 in.)
   | Max. refinishing limit:
   |  | Except KQ model: | 23.0 mm (0.91 in.)
   |  | KQ model: | 26.0 mm (1.02 in.)
   Brake disc parallelism: | 0.015 mm (0.0006 in.) max.
NOTE: This is the maximum allowable difference between the thickness measurements. If the smallest measurement is less than the max. refinishing limit, replace the brake disc. If the brake disc is beyond the service limit for parallelism, refinish the brake disc with an on-car brake lathe. 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. |
