What Causes the Squeaking Sound When Braking Slowly?

[MatteoAnn]

It is normal to hear a squeaking sound when lightly applying the brakes at low speeds. The reasons are as follows: 1. One cause of brake noise is excessive clearance in the brake pads. 2. Another reason is uneven hardness of the brake disc, leading to an uneven surface on the brake pads. 3. The slower and lighter the brake is released, the more noticeable this sound becomes. When the brake pedal is released, and the power and braking force are at a critical point, the friction between the brake pads and the brake disc produces noise. Below is some additional information about brakes: 1. Brakes generally consist of steel plates, bonded heat insulation layers, and friction blocks. They work by pressing the brake pads against the brake disc to create friction, thereby slowing or stopping the vehicle. 2. Due to friction, the friction blocks gradually wear out, so regular inspection and replacement of brake pads are necessary. 3. If the car makes a squeaking sound when braking slowly, this is normal because the brake pads and brake disc have not fully engaged to achieve tight contact and maximum friction, resulting in noise. 4. If the noise occurs during normal braking, timely repair is required.
