How do I properly replace the brake pads on my Audi A2?

I've noticed that my brakes have been squeaking and it's time for a replacement. Can someone provide me with detailed steps on how to replace the brake pads on my Audi A2?

To properly replace the brake pads on your Audi A2, first make sure to park on a flat surface and engage the parking brake. Then, remove the wheel and locate the brake caliper. Use a wrench to loosen and remove the bolts, then carefully remove the caliper. From there, you can remove the old brake pads and replace them with new ones, making sure to properly align them with the caliper. Lastly, reattach the caliper and wheel, and repeat for the other wheels.
