removing brake rotor

hi guys

I bought an 2001 6x6 big foot and I am trying to get the brake rotor off on the clutch side and I am not having much luck with it... it seems to be seize on there pretty bad just wondering if anyone had any idea on how and what to use to get it off im after putting heat on it a few times and still no luck...any help would be appreciated

thanks kevin

When I had to remove mine I have to destroy the clutch to get it off. I soaked it with PB blaster, brake fluid, and heat. It was frozen on. Used a puller with no luck. Finally with a sledge I was able to get it to move but it broke the clutch. When i put the new on on I used anti sease. good luck
