How do I change the rear brake pads on my Audi A8?

I've noticed that my rear brake pads on my Audi A8 are starting to wear down. How can I change them myself?

First, you'll need to lift the car off the ground using a jack. Then, remove the wheels and locate the caliper. Use a wrench to loosen and remove the caliper bolts. Next, slide the caliper off the rotor and remove the old brake pads. Install the new pads and lubricate the caliper bolts before reattaching the caliper. Finally, test the brakes before driving the car.
