Yeah, I screwed around for two months trying to get the Navajo system. The product might be good, but the customer service stinks.
I ended up ordering the "A-Team" setup from Southwest Performance:

I had 38 year old factory power brakes on my Scrambler before, so the bar was set pretty low, but I'm happy with the new setup so far. I'm running 33" tires, and I can lock up the wheels at neighborhood speeds if I really need to.
If I were running bigger tires, or wheeling a lot in steep terrain, I could certainly see the benefit of hydro-assist brakes, though.
I installed new stainless brake lines and calipers at the same time, but I cleaned and re-used my existing combination valve. SWP also offers a kit with a new combination valve, if you need one.
Have fun!
