Kia Optima: Disc Brake Wear IndicatorsYour vehicle has disc brakes.
When your front brake pads are worn and it’s time for new pads, you will hear a high-pitched warning sound from your front brakes. You may hear this sound come and go or it may occur whenever you depress the brake pedal.
WARNING - Brake Wear
This brake wear warning sound means your vehicle needs service. If you ignore this audible warning, you will eventually lose braking performance, which could lead to a serious accident.
✽ NOTICE
To avoid costly brake repairs, do not continue to drive with worn brake pads. Always replace brake pads or linings as a complete front or rear axle sets.
Please remember that 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.
