Condition

Some customers may comment on an excessive squeak and/or a squeal noise from the front brakes while stopping, usually during light to moderate brake applications.

Note that some brake noise is normal. Refer to the Brake Noise section of Corporate Bulletin Number 00-05-22-002F.

Correction

Verify the brake noise is being generated by the front brake pads. If the noise is from the front brake pads, install the new brake pad lining kit.

Important:
^ Rotor friction surfaces must be returned to an unburnished condition.





^ Do not replace the brake pads after the VIN breakpoint shown because these vehicles are already equipped with the updated brake pads.

1. Replace the front brake pads with P/N 15808204. Refer to Brake Pads Replacement - Front in SI.

Important:
Disc brake rotors should only be refinished if they have adequate thickness to be refinished. Refer to Brake Rotor Thickness Measurement in SI.

Brake rotors should NOT be refinished if one or more of the following conditions exist:

^ Inadequate rotor thickness

^ Thickness variation in excess of the maximum allowable specification

^ Excessive corrosion/rust and/or pitting

^ Cracks and/or heat spots

^ Scoring of the disc brake rotor surface in excess of the maximum allowable specification

2. Refinish the front rotors. Refer to Brake Rotor Refinishing in SI.

3. Road test the vehicle and burnish the new front brake pads. Refer to Burnishing Pads and Rotors in SI.
