What you need to do is to get two metric bolts that will thread into the machined holes on the face of the brake drum. Make sure that the vehicle is securely supported and the emergency brake is off. Thread the bolts into the threaded holes to "press" off the drum, do this fairly evenly or the drum will bind. When the drum is off try not to breathe the dust (contains abestes)and wash your hands after, you can clean the brakes by hosing the brake dust off with a garden hose and it is just that easy.
