Brake Pad: Procedures
Brake Pads - Inspection
INSPECTION
Visually inspect brake pads for uneven lining wear. Also inspect for excessive lining deterioration. Check the clearance between the tips of the wear
indicators (if equipped) on the pads 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 from the vehicle.
Measure brake pad minimum thickness (1). Brake pads must be replaced when usable material on a brake pad lining (2) measured at its thinnest point
measures one millimeter (0.04 inches) or less.
If a brake pad fails inspection, replace both disc brake pads (inboard and outboard) at each caliper. It is also necessary to replace the pads on the
opposite side of the vehicle as well as the pads failing inspection to maintain proper braking characteristics.
If the brake pad assemblies do not require replacement, be sure to reinstall the brake pads in the original position they were removed from.
NOTE: It is important to inspect both front and rear brake pads during the same inspection.
Brake Pad Burnishing
BRAKE PAD BURNISHING
CAUTION: After installing NEW brake pads, keep in mind that braking effectiveness might be somewhat reduced during the first brake
applications.
When NEW brake pads are installed on a vehicle, this procedure must be used to correctly burnish (seat) the brake linings to the brake rotor discs.
1. Accelerate the vehicle to a steady speed of about 40 mph (65 km/h).
2. Using light brake pedal pressure, slow the vehicle from 40 mph to 0 mph in approximately 6 seconds.
3. Accelerate back up to 40 mph for approximately one minute to allow the brakes to cool down.
4. Repeat this procedure 15 to 20 times to correctly seat the brake lining material.
