Rear rotors stuck on 01 S80 t6
 

I'm working on my mom's car and I'm trying to remove the rear rotors. They seem to be stuck on even after I've removed the calipers, pads, and that small retainer bolt. Please help. Any suggestions on how to get them off???

They are rusted on! Just use a hammer to knock them off! A few blows will loosen them.
