When this occurs, the shift lever has to be yanked out of park, and sooner or later, the pawl breaks.

If I remember correctly, Ford did use cables for brakes in 36/37, but that was obviously short lived. My grandfather bought a 1934 Ford BB in 1941 that has mechanical brakes. I would estimate the truck weighs at least 6000# empty. That truck stops quite well considering there are only metal rods actuating the brakes.

That's because it IS a parking brake. The manufacturers specifically call it a parking brake because they don't want people to get the impression that it's an emergency brake. A true emergency brake would (1) operate on all four wheels, and (2) not hold position like the parking brake (i.e. it would release when the user releases pressure). The fact that the parking brake locks in position, along with the fact that it's mechanical and not hydraulic, is what makes it a parking brake.
Back to the OP - why is everything wet? Did you just lube it with something? If not, you may have a hydraulic leak back there. As said, would be best just to get a complete rear drum hardware kit and replace it all. Some kits come with that cable and some don't. You'll need to see a pic of the kit you're ordering to be sure. Do ONE side at a time, so you have the other for visual reference.
And as said above, look into a possible wheel cylinder leak.

I was able to disengage what was left of the 'parking brake' .. which was definitely grabbing. Whatever caused the cable to snap kept it engaged. Now the truck doesn't grab .. so at least that part of the issue has been resolved.. now to go ahead and replace all the cables etc.. the shoes are actually in good shape so I'm not going to replace those at this time.
Thanks everyone for your input!!
Cheers

If it is the only option to stop a crash it is an emergency brake. If you use it improperly it can cause a crash.
I think you are missing the point.
Maintain your "parking brake" like your life depends on it. It might be the only thing that can save you someday in an emergency.
Don't think it is not important because it is sometimes called a "parking brake". Don't get lazy and ignore its upkeep because it is sometimes called a "parking brake".
The legal dept and the bean counters can't risk lawsuits. They call it a "parking brake" so you can't blame them for your stupidity if you crash.
It is a parking brake when you want a parking brake. I use it to take the load off my transmission in park like was mentioned above.

So, with one hand on the release, one hand on the shifter, how do I steer?.....
Um, you maintain it BECAUSE it's a parking brake.
Agreed, the mfr's are doing CYA, not wanting to call it an emergency brake. But if that were ever its expected function, it would operate the FRONT brakes, which do 80% of the stopping.

Years ago an old guy was telling me about how the brake rods would stretch over time and they had to shorten them.
If you have a handbrake learn to grab it without looking and with your thumb on the button so it doesn't lock when you apply it, for emergencies, or stunts, or to snuff the brake lights.
Stunt cars have separate front and rear brakes to slide the car in chase scenes and such.
