What could be causing my Audi 80 to make a strange grinding noise?

Recently, my Audi 80 has started making a loud grinding noise whenever I accelerate or decelerate. It seems to be coming from the front of the car. What could be causing this and what should I do about it?

It sounds like the brakes may be worn down and need to be replaced. I would recommend taking your car to a trusted mechanic to have them inspect the brakes and replace them if necessary.
