Hi,

You did not specify what model you have, however almost all Mitsubishis use floating rotors. This means that once the caliper is removed, the rotor is free to slide off.

There are two things that will prevent this from occurring on floating rotors. If the rotors have never been removed and it is a late model vehicle, there can be philips screws bolting them to the hub. Look around the bolt circle area where the lugs went on and you may see one or two flush philips screws. These are holding the rotor flat to the hub for assembly line reasons (they can be discarded once removed). It is preferred to have an impact screw driver to remove these, else cut them out. A standard screw driver will not usually get them.
Second, just plain environmental reasons can cause the rotors to stick badly to the hub. In this instance you have two options. You can take a block of wood and place it behind the rotor where the caliper attached and hit it with a hammer, or if you see two threaded holes around the bolt circle face of the rotor you can insert two M10x1.25 screws and evenly tighten them, effectively pressing the rotor off.



The exception to the floating rotors are a very few number of trucks have hub based rotors. Challenger/Pajero Sport, Triton/L200. On these models there will be a large protrusion through the center of the rotor with bolts holding a hat on. Under these bolts/hat will be a lock ring held on with two philips screws, then a lock ring that slides off to expose a large lock nut.... a ring with two offset holes to tighten/loosen it. Loosen the nut all the way and the hub/rotor will release. The rotor can then be unbolted from the hub from behind, or you can purchase assembled hub/rotors as well. The hubs must be pre-loaded as they are roller bearings, not sealed bearings.
Again these only apply to a narrow range of the mid sized trucks. All other models will have floating rotors.
