The tires on my 62 Plymouth are brand new. Tires on the GTX are almost 10 years old already!! Time flies. But no cracks and rubber is still soft. The D250? I'm surprised they hold air with all the cracks in them. Fronts have steel studs lol.
Found a new project. Ram D250

With the front wheels off, I cracked the bleeders and pressed the pedal. No fluid being pushed. I have new hoses ordered thinking they might be collapsed internally. The caliper boots were tore, so I popped the pistons out and they weren't stuck. They look serviceable with a rebuild kit. It got dark so I came in. Pedal has decent pressure but I'm not certain the master cylinder is good. I'll see if the hoses do the trick before I buy a new master.

Was/is the master full? Bench bleed it, you may be surprised 
Front, small chamber was a bit low. Rear chamber was full. I have the fittings soaking in Kroil to take them off.Was/is the master full? Bench bleed it, you may be surprised

That's a good sign
any crusties floating around?
Looked dark, I didn't see any crusties.That's a good sign
I have the calipers soaking in Evapo-Rust. The fluid in them looked clean. No rust inside the caliper.
Some pics of the brakes. I dipped my finger in the master cylinder and there was black sludge on the bottom. Calipers cleaned up nice and both are Mopar units. Rebuild kits on the way.
2 different pistons. Looks like somebody's been in there before. If it was me I would get me another aluminum piston so they both be the same. I've had issues with those plastic/bakelite pistons.
Well the rebuild kit for the calipers was half a success. One went together fine. Outer seal gets tapped into the housing. The other has a different style outer seal that tucks into a groove. Passenger side. So I will have to order a new one, unless someone knows the other kit part number.
But I got the driver side done. New hose, rebuilt caliper, new shoes. There was a little play in the bearings so I adjusted them, and cleaned out the dead spiders.
On to the master cylinder. Pumped out the reservoir, removed the lines and mounting bolts (brake lines came apart perfectly on both the MS and flex lines!).
Lots of gunk inside. The pistons needed assistance to come out of the MS. The front spring/piston needed some pressurized air...POP!! After cleaning them up, the seals are very pliable with no cuts, rips or tears. Looking into the bore, it looks good. No signs of pitting.
MS goes into Evaporust to soak until tomorrow, when I put it back together and attempt to bench bleed.

Well, no love with the master. It seemed to bench bleed ok. Once I put it in, it wouldn't push any fluid. I pulled the proportioning valve and ran air through the passages. Lines were clear to the calipers. Couldn't pull fluid with a vacuum pump either.
This might be a shock, but the upper ball joints are bad and need replaced, too.

Sounds like there were multiple reasons it was parked. It's going to be a good truck when you get done though, and you'll be able to make some money on it if you ever sell it.
Mechanically, it's a wreck lol. One piece at a time and it will be drivable... eventually. My friend should be by with the engine tomorrow after work.
I haven't even looked at the rear brakes. I'll save that surprise for later. I'm hoping a new master gets the brakes going first of all.
