I can not remove the old rotors

Hi Jim,

If this is the first time they have been removed some models have a spring clip on at least 2 of the wheel studs that need to be removed. Also they may have rusted on so you will need to spray some WD or similar around center and wheel studs. Let set awhile then take a hammer and hit inbetween each stud, give it a good wack, to break the rust loose. You should also hit the top of the rotor to help break it loose.
