What Causes the Noise When Braking a Car?

[Anderson]

There are several reasons for noise when braking a car: 1. If there is a slight squeaking sound at the pedal position when lightly pressing the brake while the vehicle is stationary, this is mostly caused by the return spring of the brake light switch on the brake pedal; 2. If there is a noticeable squeaking sound when braking at low speeds, the noise comes from the brake disc area. Many new cars or those that have recently had their brake pads replaced often experience such braking noise issues during driving. The steps to check the brakes are: 1. Inspect the brake pads. The effectiveness of braking largely depends on the condition of the brake pads, so checking whether the wear level of the brake pads is normal is crucial for ensuring braking performance; 2. Check the brake fluid. It is important to consider the weather characteristics of your location and destination to prevent excessive moisture from entering the brake fluid, which could adversely affect braking.
