How to change rotor on Buick?

I've just changed a rear rotor of my 1996 buick regal. 1. Jack the car up and Remove the wheel 2. Use a 19 socket wrench (same size with wheel nut wrench) to loose 2 Caliper nuts (it is difficulty, they are too tight, need a hammer) 3. Remove caliper 4. Remove the rotor 5. Clean surface then assemble them Sorry, I am a new immigrant with a pool English. But it is really so easy to change a rotor. It is the first time to change it for me, it took me 40 minutes but save $100. I bought a new rotor at Canadian Tire, just 24 dollar.
