Why do my brakes squeak on my Audi A4?

I've noticed that when I come to a stop, my brakes on my Audi A4 make a high-pitched squeaking noise. Could this be a sign of a larger issue?

Squeaky brakes on your Audi A4 can be a sign of a number of things. It could be something as simple as dirt or dust on the brake pads, which can be easily cleaned. However, it could also be a sign of worn brake pads or rotors, in which case they would need to be replaced.

Another possible cause of squeaky brakes on your Audi A4 could be a lack of lubrication. This can be easily fixed by adding some lubricant to the brake pads.

If you've recently had your brakes replaced and they're still making noise, it could be due to cheap or poor quality brake pads. Consider investing in higher quality pads to prevent this issue in the future.
