Thickness and Parallelism

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. However, it is still accessible from the selected car via links, so may be relevant.

Raise and support the vehicle (see LIFT AND SUPPORT POINTS ).
Remove the front wheels.
Remove the brake pads (see FRONT BRAKE PAD INSPECTION AND REPLACEMENT ).
Using a micrometer, measure 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: 27.9-28.1 mm (1.098-1.106 in.)

Max. refinishing limit: 26.0 mm (1.02 in.)

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

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

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 ).
Inspect the brake disc runout.
