On my 1/2 ton 62 GMC pickup when trying to remove the rear drums the shoes are stuck and will not let the drums off. I tried backing the adjuster all the way off spraying the wheel studs with pentrating oil hitting with hammer, but nothing I tried will make the shoes move in to let the drums off. Any ideas on how the remove the drums would help. Thanks
Charles.

There's a few things you can try. One thing that may be holding it up is rust on the hub itself, rather than the shoes grabbing a ridge. Try rapping the drum between the studs to loosen it up. You may have to get behind the drum with a prybar to apply pressure while rapping the drum with a hammer. A brass hammer is preferred for this, as it is far less damaging to the drum. Once it seems to move, try prying 180 degrees out to "walk" the drum off. I've used this method many times, especially on vehicles that have no provision for backing the adjuster off. It will take a little time to do to prevent damaging things, but it does work.

If the brake shoes are stuck to the drums some drastic action may be required??....after all else fails.
I had one do that and I hooked a chain to the vehicle and started pulling it with my other truck. The wheel slide for about 10 feet then popped loose and started turning. I also had a friend walk beside it and give it a good whack in the center of the wheel. Once it broke loose the drum came off easy.

May not be a very nice way but it worked and no damage was done.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile

If the shoes are frozen to the drums and will not release, try cutting the heads off the "nails" that secure the shoes to the backing plates. Take a small angle grinder with a cutoff wheel, and grind away the head of the nail. The shoe and drum assembly can then be pried away from the backing plate far enough to get a pry bar inside the drum and dislodge the wheel cylinder pins. If things are that bad, you'll probably end up replacing everything inside the drums anyhow.

The way we got the rear drums off of Number Seven was the old "Beat and Pry" method that Bill mentioned.

A little of your favorite penetrating oil used in conjuction will help things along, too.

Since things are bad enough that you have to beat and pry the drums off, you'll probably want to replace everything anyhow. Don't worry about sparing the parts unless you can't get them anymore. (Finding drums can be a problem on the older models, not sure about your year.)
