Why do my brake pads on my BMW M3 make a grinding noise?

I recently noticed that my BMW M3's brake pads are making a grinding noise every time I come to a stop. It seems to be getting worse over time. What could be causing this and what should I do about it?

This could be due to worn brake pads. It's important to get them replaced as soon as possible to avoid any potential safety hazards while driving.

Another possible cause could be a buildup of debris or rust on the brake rotors. It's a good idea to get your brakes cleaned and inspected regularly to prevent this issue.

It's also possible that your brake calipers are not sliding properly, causing uneven wear on the brake pads. I suggest getting them checked and serviced by a professional mechanic.
