Why is my Audi A5 making a grinding noise?

I have noticed that my Audi A5 has been making a grinding noise when I apply the brakes. What could be causing this issue and how can I address it?

It is possible that your brake pads have worn down and are now grinding against the rotors. It is important to have this checked and replaced if necessary as it can lead to further damage and potential safety hazards.

Another possibility is that there could be debris caught in the brake caliper, causing the grinding noise. This can usually be resolved by cleaning out the caliper, but it is best to have a professional inspect it to be sure.

In rare cases, the grinding noise could be due to a malfunctioning ABS system. If you notice any other unusual behavior with your brakes, it is important to have it checked by a mechanic as soon as possible.
