cant get my rear brake drum off.I used hammer.then 2 12mm bolts.

can you use 12mm bolts?

See previous post

MOST LIKELY THE SHOES HAVE WORN INTO THE DRUM AND THEY HAVE CREATED A RIDGE. YOU WILL NEED TO BACK THE ADJUSTER OFF ENOUGH FOR THE SHOES TO CONTRACT. THE SELF ADJUSTING LEVER USUALLY NEEDS TO BE PUSHED AWAY FROM THE ADJUSTER TO TURN IT BACKWARDS. ONE OF THE PARTS HOUSES CAN GET YOU A PICTURE OF THE DEVICE T SEE WHAT YOU NEED TO DO. GOOD LUCK
