Answer
Art you should be able to tap the drums with a hammer while your pulling to free them up. If that doesn't work the holes are for turning in a bolt to push of the drums. However you will probably just strip them out. I haven't seen one yet that hasn't. The holes will be a metric thread. Probably an eight mill. x 1.5. The last thing you want to do is pry on them you will just bend up your backing plate.
