Brake Disc Thickness Check

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

    32.0 mm (1.26 inch) < Front > 

    22.0 mm (0.87 inch) < Rear > 

    Limit: 

    30.0 mm (1.18 inch) < Front > 

    20.0 mm (0.79 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.
