Thickness & Parallelism

WARNING: This page is about a different variant/trim than selected.

Raise and support vehicle. Remove wheels. Remove brake pads. See FRONT DISC BRAKE PADS  under REMOVAL & INSTALLATION. Using a micrometer, measure disc thickness at 8 points approximately 45 degrees apart and .4" (10 mm) in from outer edge of disc. Replace brake disc if smallest measurement is less than the MAX. refinishing limit. See DISC BRAKE SPECIFICATIONS .

  1. Brake Disc Thickness (Standard) -  .82-.86" (20.9-21.8 mm)
  2. Brake Disc Thickness (MAX. Refinishing Limit) -  .75" (19.0 mm)
  3. Brake Disc Parallelism (Maximum) -  .0006" (.015 mm)
NOTE: This is the maximum allowable difference between the thickness measurements.

If the disc is beyond the service limit for parallelism, refinish brake disc with an on-car brake lathe. If it is beyond service limit for refinishing, replace the brake disc. See BRAKE DISC (FRONT)  under REMOVAL & INSTALLATION.
