So I got back from the last wheeling trip without problems, or so I thought. I've lost all brake pressure and my brake light is on. I bled and serviced the system and took it for a drive. Driverside front brake started dragging about 2 miles from the house, 3 stop signs and a red light later. It was dragging so bad I could feel the heat on my feet through the floorboard. I milked it back home, took caliber apart, reassembled and bled and serviced again.
Went for another drive, everthing seemed alright until my passenger side front brake started dragging. Pulling hard to the right and hardly any brake pressure. Milked it home again and by the time I got there it was fine.
Got under and started looking at all my lines and noticed a rubber plug missing on the rear passenger drum housing and fluid everywhere. Bought new plug, installed and fluid continues to come out.
Long story, well still long, I'm pretty sure I have a piston seal blown inside the drum. Problem is I can't get the drum off. I've tried loosening the spoon via the little access hole on the housing and I'm pretty sure I've reached the end of the threads. I know I can probably pound it off but I don't want to break the drum or the housing.
Any ideas or suggestions would be great.

Your wheel cylinder is where the fluid is coming from. You already loosened the auto adjuster so.....First thing is to smack the drum around the face to help free it if it is rusted to the hub. Then rotate as you pull it off.
If all else fails you can cut the heads off the brake shoe pins... be careful in doing so because all the springs will fly everywhere once the drum is pulled off...

If you have the brake adjuster all the way backed off then your drum is rusted to the axle. Get out you BFH and be as gentle as you can. Try hitting it with some PB Blaster first.

With some paitence it will come off, with wheel off and the car stable, spray some PB Blaster around the outside center hub, your local parts store will probably rent or loan a drum puller. After letting it soak, set up puller and with moderate pressure hammer around the drum. It should "PoP" free.

Stock up on plenty of clean rags and some spray brake cleaner. A wheel cylinder and shoes are pretty inexpensive. Don't cut corners and reuse the soiled shoes, chances are good they are ruined.
