In regards to your issue, i'm geussing you cant get the rotors off.
1st of all I beleive on the rotors there is a screw that holds them in place, usually an allen head, 1st remove that. Since the description isn't that great i'm also guessing that you need to remove the caliper bracket that would more then likly have a couple large bolts in the back to keep it there, they are usually on there pretty good and my suggestion is to get a ratchet and a breaker bar and goto town, also apply some wd40 or pb blaster to help and make it easier to get the bolts off.
After you have that off if the rotor wont come off, get yourself a peice of wood and a hammer and hit the rotor from the back, hard enough to persuade it to come off of the hub.
Also you should not let the calipers hang from the brake lines its bad for the lines, you should get some wire to hang them from inside the wheel well.
Good luck and hope this helps.
