How do I replace the brake pads on an Audi A5 Sportback?

I heard that it's important to regularly replace brake pads to maintain the performance and safety of my Audi A5 Sportback. Can someone walk me through the steps of doing so?

Before starting, make sure to have a backup jack and both the front and back brakes replaced simultaneously for even wear.

To replace the pads, remove the wheel and unbolt the caliper, then use a C-clamp or brake piston tool to push back the pistons before installing new pads.
