How do I change the brake pads and rotors on my Audi A2?

I'm looking to save money on maintenance by doing this task myself. Please explain the necessary steps and any potential difficulties that may arise.

First, you need to jack up the car and remove the wheels. Then, use a ratchet or breaker bar to loosen the caliper bolts and remove the caliper. Next, remove the old brake pads and rotor. Remember to use an anti-seize compound on the bolts when reinstalling.
