What are some common issues with the Audi A2 brakes?

I've noticed my Audi A2 has been having some issues with the brakes, such as squeaking and reduced braking power. What could be causing these issues and how can I address them?

One common issue that can cause squeaky brakes is worn brake pads. It's important to have your brake pads checked regularly and replaced if necessary to ensure proper braking power.

Another possibility is that the brake calipers may be sticking. This can be caused by dirt or debris in the caliper, which can be cleaned out or replaced if necessary.
