YOUR transmission does. Doesn't mean ALL transmissions do. I haven't had a vehicle with a transmission with a Park position in 35 years.

Put the shift lever into park before setting the parking brake (if it's set at all) will cause the truck to roll...just enough...that the parking pawl inside the trans will lock up.

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

That was sarcasm. "DUH" was the clue.

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.

Prior to 1939, the brakes were mechanical, controlled by adjustable rods.

"The security of steel, from pedal to wheel."

One thing about mechanical brakes, they can sit for 30 years and work fine. Not so with juice brakes...

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.
Hey just a quick note here for you - I did just spray brake cleaner on everything prior to taking the pics.. so it's not something to be concerned about.. that said however.. the piston on the driver side IS leaking... there's a lot of moisture on that side - zero on the passenger side.

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
Tyler

You can buy the cable separately for 5 bucks or so.

If you hold the release handle in your hand the brakes do not lock. You should practice this and be comfortable with it.

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.

Had a SAAB with front "parking brakes". It was cool cause it would stop straight in the snow and ice by using the hand brake. Drove in an ice storm once with cars off both sides of the Interstate for miles. We made it home ok. These days they would close the road.
