How often should I change the brake pads on my Audi A5?

I've had my Audi A5 for two years now and I haven't changed the brake pads yet. How often should I change them to maintain optimal performance?

It is recommended to change your brake pads every 20,000-30,000 miles for regular driving. However, if you do a lot of stop-and-go driving, it may be best to change them every 15,000 miles.

You should also pay attention to any squeaking or grinding noises when braking, as this could be a sign that your brake pads are worn.

Additionally, regularly checking your brake pad thickness can also help determine when they need to be replaced.
