rear drum removal
I recently obtained a 65 F100 step side. I ws checking the brakes out on the rear. I removed the left rear wheel, released the parking brake and the drum pulled right off. I attempted to do the same on the right side and I can't get the drum off. Is there something differnt on the right rear that I am missing. The parking brake is off and the drum moves so I don't think it is locked up but I can't get the drum off.

Couple of things to do.....1) loosen up the brake adjuster (star wheel- access located at the lower part of the backing plate), 2) spray penetrating oil liberally around the wheel studs and 3) get a BFH and while rotating the drum smack it on the outer circumference multiple times....that should do it!

If truck has set for any length of time the brake and adjustment assemly can freeze up and create a major pain in the backside. Found spraying brake cleaner thru every oriface possible to loosen any residual brake dust helps. Make sure to put some thing underneath, it can get messy. I have found certain tools work best for me; a soft head maul, and a wide spread flat prying tool, it basically comes down to ' backyard mechanics 101' use what ever tool available. After using the brake cleaner I begin by tapping around the perimeter of the drum and turn then give it another dose. Then use the mall, tapping while attempting to separate the drum from the shoe, may involve using a combination of both tapping and prying around the perimeter, keep in mind the drum is made of high carbon alloy and subject to break. With patience it will eventually work itself off. Had to replace the entire brake assembly on the 65, including the drum, and found local Napa parts store carried all the parts.

I agree with all. Like Beechkid said though, make sure you loosen the adjuster when you use the BFH and spray cleaner/lube trick. The shoes can wear into the drum and it may just be hanging up on a little lip created on the drum. Beating the drum free without loosening up the shoes can cause damage to more brake components.

I applied leverage between the drum and whatever with some screwdrivers and wedged them in place. A couple of hours later, while I was away, I heard a loud twang and the drum flew off a few feet away.

Wow, fortunately nobody was setting, scratching their head and staring at the drum when it finally decided to give way!! 
Sorry, forgot to mention, from setting the accumualtion of rust and dirt tends to create a tight fit between the axle and hub flange and by applying pressure from the outside of the hub it create what I would describe as a potential spring and eventually something has to give. In the future suggest try cleaning the area with brake cleaner and use a scribe, screwdriver, or simular tool, while tapping with hammar on the area, usually once the seized area is loose the hub is a bit easier to remove?

Take some light sand paper and sand off any of the rust on the axle where the drum slides over. Then use a Torch to heat up the center of the brake drum where it fits over the axle. After you get it hot take a couple of hammers and hit the outside where the brake shoes ride (at the same time) at equal spacing 180 degrees apart. After you get them off clean all the rust off the axle and brake drum interface. This works for the really stuck ones!!!!
