What is the cause of the grinding noise in my Audi A5's brakes?

Recently, I have noticed a grinding noise coming from my brakes when I apply pressure. The sound only occurs when I am braking at low speeds, and it seems to have gotten louder over time. What could be causing this issue and how can I fix it?

It is possible that your brake pads have worn down and are now grinding against your rotors. This could be due to extended use or aggressive driving habits. It is important to get this checked and replaced by a professional immediately to avoid further damage to your Audi's braking system.

Another potential cause could be debris or dirt lodged between the brake pads and rotors. It is important to regularly clean your brakes and have them inspected by a mechanic to prevent any issues.

It is also possible that there is an issue with your brake calipers or brake lines. These components can become stuck or damaged over time, causing noise and potentially affecting your braking performance. Have a mechanic inspect and replace any faulty parts to ensure your Audi A5's brakes are functioning properly.
