How do I change and replace my Audi A4's brake pads?

I've noticed that my Audi A4's brakes are not as responsive as they used to be. I suspect that it's time to change the brake pads. How do I go about doing this? Is it something I can do on my own or should I take it to a mechanic?

Changing the brake pads on your Audi A4 is something that can be done on your own, but if you are not experienced with car maintenance, it is best to take it to a mechanic. However, if you do decide to change them yourself, make sure you have all the necessary tools and consult a guide or tutorial to ensure proper installation.
