Check all four brakes for fluid leaks. If it is going to the floor, sounds like the hydro boost is working fine. A similar issue on my CUCV turned out to be one of the T shaped things on a rear wheel cylinder had came out of place and let all the rear brake fluid leak out. A pair of new rear wheel cylinders + a new T thing fixed the problem. Those T things are a bit of a pain to find. Not included with the wheel cylinder kit.
