Thickness and Parallelism

WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.
  1. Raise and support the vehicle (see LIFT AND SUPPORT POINTS ).
  2. Remove the rear wheels.
  3. Remove the brake pads (see REPLACEMENT  ).
  4. Using a micrometer, measure the brake disc/drum thickness at eight points, about 45° apart and 10 mm (.39 in.) in from the outer edge of the brake disc/drum. Replace the brake disc/drum if the smallest measurement is less than the max. refinishing limit.

    Brake disc/drum thickness: 

    Standard: 10.9-11.1 mm (0.429-0.437 in) 

    Max. refinishing limit: 9.0 mm (0.354 in) 

    Brake disc/drum parallelism: 0.015 mm (0.00059 in) max 

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

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