Grabby brakes are usually caused by the shoes getting contaminated with either brake fluid (leaking wheel cylinders) or gear oil (leaking axle seals). Pull the drums off and have a peek at what is going on.

Just read about this being another problem on these trucks. Mine always does it after it rains.

Mine too. After I let my truck sit for a while after it rains they lock up the first couple times I hit the brakes then by the time I get outta the neighborhood its fine.

Lately I've been having a constant problem like this, my wheel cylinder cracked recently though so I think as sasquatch said, the shoes are contaminated
