Front Disc Brake Pads: Inspection

WARNING: Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket brake linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. DO NOT sand or grind brake lining unless equipment used is designed to contain the dust residue.

Visually inspect brake pads for uneven lining wear. Also inspect for excessive lining deterioration. Check the clearance between the tips of the wear indicators on the pads (if equipped) and the brake rotors. If a visual inspection does not adequately determine the condition of the lining, a physical check will be necessary. To check the amount of lining wear, remove the disc brake pads. Measure each brake pad. The combined brake pad and its lining material thickness should be measured at its thinnest point. For front disc brake pads, when a set of brake pads are worn to a thickness of approximately 5/16" (7.95 mm), they should be replaced. Replace both disc brake pads (inboard and outboard) on each caliper. It is necessary to replace the pads on the opposite side of the vehicle as well as the pads failing inspection. If the brake pad assemblies do not require replacement, be sure to reinstall the brake pads in the original position they were removed from.
