What are the symptoms of a warped brake disc?

[VanNathan]

Symptoms of a warped brake disc include abnormal braking noises and vibrations during braking. In such cases, the brake disc needs to be replaced to ensure driving safety. A brake disc is a circular disc that rotates as the vehicle moves. The brake caliper clamps the brake disc to generate braking force; when the brake is applied, the caliper grips the disc to slow down or stop the vehicle. Braking systems include disc brakes, drum brakes, and air brakes. Older vehicles often feature front disc brakes and rear drum brakes, while many modern vehicles use disc brakes on both front and rear wheels. Disc brakes offer better heat dissipation compared to drum brakes, reducing the risk of heat fade during high-speed braking, which results in superior high-speed braking performance.
