Hi Joe...

Try this test (CAREFULLY!!!):
Climb under your deuce and open the drain valve on both of your air
tanks, and let out all the air.
Leave the air valves open, then (CAREFULLY) start up your deuce and
drive a short distance and try the brakes with zero air pressure. If
the feel the same as they did with full air pressure, then the problem
is probably your air pack.
If the brakes are a LOT worse or even non-existant with zero air
pressure, the problem is NOT your air pack.
As I mentioned, be very careful with this test. In my case, it turned
out that when I did this test I had literally no brakes and had to let
the truck slow down on its own and use the emergency brake.
You might want to pull off one of your front brake drums and have a
look at the brake shoes. Again in my case, the drums were soaked with
gear oil from a bad seal which was lubricating the shoes against the
drum.

Coincidentally, this month's Military Vehicles magazine (Issue #91,
June 2002) has an article on how to put that very rebuild kit to good
use and install it correctly. I have talked to several people who
have installed the kits and had them work just fine.
Just my opinions.
Good luck!
