That's weird that you mention the rear brakes not working for a while. When I bought this truck (recently) the previous owners told me they'd had the rear brakes rebuilt. Well the guy put them back together wrong and didn't properly seat the pushrods from the wheel cylinders in the brake shoes so they overextended and didn't move the rear brakes at all. I fixed all that, but the pedal feel didn't change. It could well be this front combo valve you're talking about. Got any links that talk about how to reset that? This truck does have front discs, but do you know if they had that valve in '79?
