prob a dumb question but ive never done brakes before.. this is my first car 
i took the wheel off and the retaining screw but now i cant get the drum off. i figure the pads prob cut a groove in it not letting me pull it off. the manual tells me to stick a screw driver and turn it to the brakes come off the drum. there is 3 holes on the drum and none in the back ( i believe the back is called the backing plate ???)and i looked in the 3 holes in the front and there is nothing there to turn. and i dint find any hole in the back so im stumped?
thanks agian for all the help... i figure this is the only way to learn pull it apart get stumped ask you guys...my cruiser thanks you
