How to replace the rear brake pads on an Audi 80?

I need to replace the rear brake pads on my Audi 80, but I'm not sure where to start. Can someone provide a step-by-step guide?

First, you'll need to remove the wheel and locate the brake caliper. Then, use a piston retractor tool to compress the caliper and remove the old pads. Make sure to clean and lubricate the caliper before installing the new pads. Finally, carefully reattach the caliper and repeat on the other side.

Before starting the replacement, make sure you have all the necessary tools and materials, including new brake pads and brake grease. It's also a good idea to consult an online tutorial or the vehicle's manual for specific instructions for your Audi model.
