What would be the safest way to remove my front brake rotors on my 06 ram 2500 4x4? They are pretty darn rusty and if they are anything as bad as my back rotors then I`m in for a work out. I was thinking if I beat on them them it may hurt the hub bearing. I`m putting on new rotors so I`m not worrying about saving them. How hard would it be to cut them off? Any other ideas?
