How do I change the brake pads on an Audi A4?

I need to replace the brake pads on my Audi A4 but I'm not sure how to do it. Can someone provide step-by-step instructions?

First, you will need to remove the wheels and locate the brake caliper. This is the metal component that holds the brake pads in place.

Next, you will need to remove the brake caliper by loosening the bolts that hold it in place. Be careful not to damage the brake line.

Once the caliper is removed, the old brake pads should easily slide out. If they are stuck, you may need to use a hammer or some force to loosen them.
