How do I change the rear brake pads on my Audi A3?

I need to replace my rear brake pads on my Audi A3 but I'm not sure where to start. Any advice on the steps I should follow and any tools I may need?

First, make sure you have a jack and jack stands to safely lift and support the car. Then, remove the wheel and locate the caliper bolts. Use a wrench to loosen and remove the bolts, then use a C-clamp to compress the caliper piston. Remove the old pads and replace with new ones, making sure they are properly aligned with the caliper. Finally, reattach the caliper and wheel and test the brakes before hitting the road.
