When your brake pads are worn and new pads are required, you will hear a high pitched warning sound from your front or rear brakes. You may hear this sound come and go or it may occur whenever you depress the brake pedal.
Please remember some driving conditions or climates may cause a brake squeal when you first apply (or lightly apply) the brakes. This is normal and does not indicate a problem with your brakes.
NOTICE
To avoid costly brake repairs, do not continue to drive with worn brake pads.
Information
Always replace brake pads as complete front or rear axle sets.
