Why are the brakes of my Audi A2 not functioning properly?

I recently bought a used Audi A2 and I noticed that the brakes are not as responsive as they should be. What could be causing this issue?

You may need to replace your brake pads. It's important to do this every 50,000-70,000 miles to maintain optimal braking performance and prevent damage to your rotors.

Check your brake fluid level and top it up if necessary. Low brake fluid can cause a spongy feeling in the brakes and affect their responsiveness.

There could be an issue with the brake lines or calipers. It's best to have a professional mechanic inspect and diagnose the problem to ensure it is fixed correctly.
