What Causes Squeaky Brakes in a New Car?

[OMaddox]

The reasons for squeaky brakes in a new car are as follows: 1. The newly replaced brake pads and brake discs require a break-in period, which usually takes about 500 kilometers to complete. The brake discs may have been worn unevenly by the old brake pads, while the new brake pads have a smooth surface. Therefore, the contact area is initially small and requires break-in. It is normal to hear sounds before the break-in is complete. 2. Noise caused by brake pad material: Harder brake pad materials are more likely to produce such noises, while softer materials may result in sharper sounds. If this is accompanied by reduced braking effectiveness, this is likely the cause. 3. Improper installation of the braking system can also cause noise, which is more complex and requires inspection and handling at a repair shop.
