How do I change the brake pads on a 1992 Audi 80?

I just bought a used 1992 Audi 80 and I noticed the brake pads are worn out. How can I change them myself without having to take it to a mechanic?

First, gather all the necessary tools: jack, lug wrench, socket wrench, brake pads, and brake caliper tool. Then, use the lug wrench to loosen the lug nuts on the wheel you want to change. Once the lug nuts are loose, lift the car with the jack and remove the wheel. Next, use the socket wrench to remove the bolts on the back of the brake caliper. Slide out the old brake pads and put in the new ones. Finally, use the brake caliper tool to push the caliper back into place and reattach the bolts and wheel.
