PARKING BRAKE AND BRAKE PEDAL Self-adjusting brakes Your vehicle is equipped with self-adjusting brakes. The front disc-type brakes self-adjust every time the brake pedal is applied. The rear drum-type brakes on two-wheel drive vehicles self-adjust every time the parking brake is applied. The rear drum-type brakes on four-wheel drive vehicles self-adjust every time the brake pedal is applied. If the brake pedal goes down farther than normal, it may be due to lack of adjustment of the rear drum brakes. Apply the parking brake several times.

Brake pad wear indicators The disc brake pads on your vehicle have audible wear indicators. When a brake pad requires replacement, a high pitched scraping or screeching sound will be heard when the vehicle is in motion. The noise will be heard whether or not the brake pedal is depressed. Have the brakes checked as soon as possible if the wear indicator sound is heard. Maintenance and do-it-yourself 8-29
