How to troubleshoot a strange noise from the brakes in my Audi A3?

I noticed a strange noise coming from the brakes of my Audi A3 while driving. It occurs whenever I press the brakes. What might be the cause of this and how can I fix it?

It is likely that your brake pads are worn out and need to be replaced. Depending on the severity of the wear, you may also need to replace the brake rotors. It's best to have a professional mechanic take a look to determine the exact cause of the noise.

Make sure to also check the brake calipers and the brake lines for any issues. Sometimes, stuck calipers or worn out brake lines can also cause strange noises.
