Why does my Audi 80 make a strange noise when braking?

Whenever I press on the brakes in my Audi 80, there is an unusual grinding sound coming from the front wheels. It doesn't affect the performance of the car, but it's concerning. What could be causing this noise?

It's possible that your brake pads are wearing thin and need to be replaced. The grinding noise could be the sound of metal rubbing against metal. It's important to get this checked out by a mechanic as soon as possible to prevent further damage to your brakes.
