Thickness and Parallelism

WARNING: This page is about a different car, the 2006 Honda Odyssey and 2005 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
  1. Raise the front of the vehicle, and support it with safety stands in the proper locations (see SAFETY STANDS ).
  2. Remove the front wheels.
  3. Remove the brake pads (see FRONT BRAKE PAD INSPECTION AND 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: 27.8-28.1 mm (1.10-1.11 in.) 
    • Max. refinishing limit: 26.0 mm (1.02 in.) 
    • Brake disc parallelism: 0.015 mm (0.0006 in.) max. 
    NOTE: Parallelism 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 an on-car brake lathe. The "Front Brake Disc Lathe" offered by Snap-on Tools Co. are approved for this operation.
    NOTE: If the brake disc is beyond the service limit for refinishing, replace it (see KNUCKLE/HUB REPLACEMENT ).
