On my former 47 Chrysler Coupe, I rebuilt the entire braking system, but used the drums, had those machined on a brake drum lathe.
I adjusted the major adjusters to factory spec, witrh arrows pointing in the direction in the service manual.
Once I bled the brakes very well, I did use DOT 5 silicone brake fluid, I had a decent pedal.
The brakes at first were just so-so, after several hundred miles, I would do a minor adjustment, this I continued for another several hundred miles.
Once the brakes shoes wore into the drum radius, they were awesome, I could hit those brakes and put a passenger into the dash no problem.
Bob H aka Dodgeb4ya, gave me this recipe and it worked well.
When brake jobs were done years ago, brake shoes were shaped on the arcing machines to have maximum contact with the drum surfaces, so instant good brakes, the other way is to wear this in, and to do periodic brake adjustments.
Bob also mentioned that he owns the Ammco and/or Miller brake tool for thee Lockheed systems, but that he hardly used them.
What I am getting at, is you can still have good brakes, without those tools, but you must find a method to create maximum/total contact.
Some on this fourm have made brake adjusting tools, and have used those to get those shoes dialed in better.
Good Luck
