Thanks but that isn't it. On the rear brakes of the 3/4 ton, there are no hold downs like that. There are in the front. The shoes are pinned to articulating joints which can only be driven out toward the inside of the truck. This is not possible until the assembly is removed from the backing plate. I am trying to avoid removing the axle shaft and hub but if I do that, I can remove the entire two-shoe assembly in one piece and work on the bench.
The seal is leaking badly, so maybe I will have to remove the hub anyway. Nevertheless, the manual says the shoes can be removed with the hub in place.
These Huck brakes are not very standard: at least not anymore. I'd bet the local auto store won't have a clue.
