Brake Disc Thickness Check

WARNING: This page is about a different car, the 2013 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove contaminants or corrosion from the brake disc surface.
  2. Use a micrometer to measure the brake disc thickness at minimum eight points which are 10 mm (0.39 inch) inward from its circumference.

    Standard value: 

    26.0 mm (1.02 inch) < Front > 

    10.0 mm (0.39 inch) < Rear > 

    Limit: 

    24.4 mm (0.96 inch) < Front > 

    8.4 mm (0.33 inch) < Rear > 

  3. If the brake disc thickness is worn beyond the limit value at more than one point, replace the brake disc and check its run-out.
