If you are speaking of the Torx set screw that holds the rotor to the hub, often times this gets seized due to rust. A trick to get this out is with some rust penatrent. If it still is stuck you may need an impact driver and a hammer to get it out fully. Also if you don't have a Torx bit to fit the screw, these can be purchased at auto parts stores.
