How do I replace the rear brake pads on an Audi 80?

I recently noticed that my Audi 80's brakes weren't as effective as before and after inspection, I found that the rear brake pads need to be replaced. Can someone provide a step-by-step guide on how to replace them correctly?

First, make sure to park the car on a flat surface and put wheel chocks on the front wheels to prevent the car from rolling. Loosen the lug nuts on the rear wheels, then lift the car with a jack and secure it with jack stands. Remove the wheels and caliper from the rear brakes. Replace the old brake pads with new ones and reassemble the brake components back in place.

Before beginning the process, make sure you have all the necessary tools such as a wrench, jack, and jack stands. It is also recommended to have a service manual specific to your Audi 80 model for reference. Also, don't forget to lubricate the caliper slider pins for smoother brake operation.
