2004 Kia Sorento brank rotors R&R

I have a 2005 Kia Sorento 4x4 and need to change the disc pads and have the rotors machined. I have removed the caliper assembly and the two phillips head screws that should hold on the rotor. Using a rubber mallet I cannot get the rotors to budge. I also put a wheel puller on the studs and then the puller bolt on the axle shaft and tightened, still no luck. Would the emergency brake effect the front wheels? Thanks.
