What Causes the Abnormal Noise When Braking in a Chevrolet Cavalier?

[StAngela]

There are several reasons for the abnormal noise when braking in a Chevrolet Cavalier, including normal ABS activation, rust on the brake pads or brake discs, and excessive wear of the brake discs and brake pads. Normal ABS Activation: Normal ABS activation is a common phenomenon. The ABS operation involves a cyclic process of locking and releasing, keeping the vehicle in a state of near-lock rolling. When the ABS is activated by hard braking, it may produce abnormal noise. In this case, simply press the brake pedal firmly to the floor. Rust on Brake Pads or Brake Discs: After prolonged parking, especially in humid or rainy conditions, rust or dirt may form on the brake discs or brake pads. This issue can usually be resolved by driving for a while. Alternatively, applying butter or specialized lubricant at the connection between the brake pads and brake calipers can help. Excessive Wear of Brake Discs and Brake Pads: Brake discs and brake pads are high-wear components that experience friction every time the brakes are applied. Long-term use leads to wear, and excessive wear can cause abnormal noise. Therefore, regular inspection and replacement are necessary.
