Analysis of Brake Noise Issues in Winter for Audi A6

When driving an Audi A6 in winter, owners may notice a noise coming from the braking system.

This phenomenon is common in cold weather conditions where frost may form on the brake discs, leading to rust.

Additionally, the contraction of parts in low temperatures can also trigger slight brake noise. Typically, this noise disappears after driving for a while.

If the brake noise is particularly loud, it is advisable to consult a 4S shop to see if grinding the brake discs can resolve the issue. There are various factors that can cause brake noise.

To determine the specific reason, it is necessary to assess the noise situation, ideally in person.

Here are some common scenarios for reference:

1. For new cars, slight noise may occur during the break-in period as the brake pads and discs make contact. This is normal and will usually disappear after a few hundred kilometers.

2. Driving in adverse weather (such as windy, rainy, or snowy conditions) may allow particles to enter the brake system, causing abnormal noise. In this case, repeatedly applying the brakes can help dislodge the particles and eliminate the noise. If the noise persists, the brake discs may need to be removed for thorough cleaning.

3. For vehicles parked for extended periods, brake pads may also produce noise. Drivers can resolve this by driving for a short time and applying the brakes several times. If this does not help, the brake pads may need to be removed and cleaned. It is advisable to seek professional assistance.

4. If the brake system is malfunctioning, it could indicate severe wear on the brake pads, necessitating timely replacement to ensure driving safety.
