Roger--------some brake drums are held onto axles and or hubs via the studs pressed thru from the back---------


Also if this vehicle still has MECHANICAL brakes, the cables are probably where its rusted/frozen up.


Sometimes you can break free up by flexing the cable housings and that will loosen the cable--used to have to do that to the parking brake on my truck before every 6 month state inspection-now law has been changed on B plates--


wear goggles while under that thing
