Thickness and Parallelism

WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.
  1. Raise the vehicle on a lift (see LIFT AND SUPPORT POINTS ).
  2. Remove the front wheels.
  3. Remove the brake pads (see REPLACEMENT  ).
  4. Using a micrometer, measure the brake disc thickness at eight points, about 45° apart and 10 mm (3/8 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: 21.0 mm (0.827 in) 

    Max. refinishing limit: 19.0 mm (0.748 in) 

    Brake disc parallelism: 0.015 mm (0.00059 in) max. 

    NOTE: This is the maximum allowable difference between the thickness measurements.

  5. If the brake disc is beyond the service limit for parallelism, refinish the brake disc with a Honda-approved commercially available on-car brake lathe.
    NOTE: If the brake disc is beyond the service limit for refinishing, replace it (see FRONT BRAKE DISC REPLACEMENT  ).
  6. Install the brake pads (see REPLACEMENT  ).
  7. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the front wheels.
