Front Rotor removal trouble...

I am working on my 1999 Isuzu Trooper and i am trying to remove/replace my front rotor. I haven't done this on a trooper before and i am having difficulty doing so. I have the caliper and caliper bracket, dust cap, and the metal hub thinger removed (the piece held on by the spring clip). The rotor spins independantly of the metal hub thing in front of it, and they both look like they should just pull off, but I didn't want to pound the crap out of the rotor when i didn't know for sure if that was how it came off. So any help with the my rotor removal issues would be greatly appreciated!!

Thanks in advance,
Brad
