I think I would check to be sure the calipers can float on the mounting brackets like they are suppose to. As this stuff is getting older, the hard parts are showing up with wear we have not had to look at before. For instance, if the ears the front pad sit on have a little dip in them, the pads get hung up in the dip and won't move freely like they should. The result is poor brakes.
The same deal with the drum backing plates. The little raised pads the brake shoes sit against are suppose to be flat and smooth. Any roughness or wear will hang up the shoes from moving like they are suppose to, resulting in poor brakes.
I'm seeing a lot more brake issues then we ever saw before. I'm sure some of those issues are related to the off shore parts we seem to be stuck with, but a lot of issues are with older vehicles. I suspect we are beginning to see the always reused brackets and backing plates that are beginning to have wear we have never had to look at in the past.
The last Dakota I did (91 model year) had groves where the front brake pads sat that I ground clean, welded back up and sanded smooth, and the rear drum backing plated had groves where the shoes sat. I also ground them off, welded them up and ground them flat. The brakes on that Dakota are the best they have been since I've owned the truck.
Dodge put that truck together in 77 and I suspect the brakes were fine then. If the parts you have put on are functioning (holding fluid and have a solid pedal), its time to look at what else may need to be fixed before you start swapping out masters that may or may not overcome the worn parts.

I've read about seating the pads and shoes by getting up some speed and then jamming the break pedal hard to get them seated. Might help. Another thought, I once put new discs & pads on and forgot to clean the oil off the discs first with brake cleaner. Those suckers wouldn't stop on a 20 dollar bill, let alone a dime. I cleaned the discs and put new pads on and it stopped on that dime and gave 9 cents change. It was on my '78 D-100.

I think the semi metallic would stop better. They just wear things down faster. That's due to the small bits of metal in them. Might have to go back and check your hydraulics, as many have suggested above.

Metalic pads need a lot of heat (friction ) to work . without power assist theres no way to put enough pressure on them to work right . put a power booster on the truck or get the right pads. Not sure if you can get "organic" pads any more. Your pads are too hard.

Manual brakes may take more effort to use. They should not apply less pressure. I myself prefer manual. Brakes and steering. Wouldn't have thought the pads themselves were the issue. Good info for future use. Also glad you got it figured out.
