The Hydroboost unit looks pretty good, but you need a power steering pump to supply it.

I used a remote vacuum brake booster when I built my Arntz 30 years ago. Originally, I had a single system which supplied boost to all four wheels. That worked well, but I was concerned that if one thing fails, I could lose all braking capability.

Then, I rebuilt the system with a balance bar and twin Wilwood master cylinders that separated the front and rear hydraulic circuits. I installed an adjustment knob inside the car. I took the remote booster out. This did not work so well because I could not make my pedal ratio 6 to 1. There was not enough space because of the under floor arrangement. I just could not push hard enough to lock up the front wheels. The new rear ventilated disks WOULD lock up, which was very scary!

So, I put the remote brake booster back in and connected it to the front circuit only. It was difficult to get the balance right until I put a Wilwood adjustable proportioning valve on the front circuit, too. Now, I have complete control of the brake pressure and can set the balance for one or two people or for the amount of fuel in the tank. The pedal pressure is moderate and comparable to any modern car. However, it stops so hard (when necessary) it stalls the engine. That is a carburetor problem and I am working on it.
