67 C20 rear brake locked up

[gale]

Has anyone knocked out the plugs in the backing plates to get at the adjuster?

My rear brakes are locked up and I need to release the shoes so I can move the truck. Brake lines are disconnected so there is no hydraulic pressure.

Yes, I've done it. Sometimes it's easy and other times it's a pain. Before you do that give us some background. Did you just do a brake job or did they lock up on their own after driving it?

If it's he latter, loosen the bleed valve and see if the pressure is released. If it does release, you may have obstructed rubber brake line hose on the rear above the axle shaft.

has the truck set like that for a long time??
it could be that they are rusted and that is the cause of the problem// in that case i'd try putting it in reverse and gasin it to break it loose

The truck hasn't been driven in 5 years. The hydraulic lines are cut so there is no pressure. They needed replacing anyway. Previous owner rounded the bleeder valves so I'll just replace the wheel cylinders. But for now I need to move the truck from behind my shop to inside. I planned to pull it with another truck but I didn't want to have to drag it.

Last time I had it running was to park it under a shed and the rear wheels were just about locked up then (2011) and I figured I'd deal with the brakes when I started work on the truck. Now I'm ready to move it into my garage.

I do have a cutting torch and I thought about just wasting the drums but it seems to me the brake linings are all that's keeping this from rolling and I wouldn't think they would rust.

Latest in my saga...
I wrapped the chain from a CM puller around the tire and pulled from the rear end of the frame (bed is off) and the wheels reluctantly turn but at least now I think they will roll and not just skid the tires.

Perhaps it will free up as I tow it about 100 feet. I'm going to need to roll the chassis around by hand.

Hope to see some pics of your progress on this truck.

Got it moved. What is the best way to post pics of work in progress?
