I'll tell ya what Ken. If the mechanicals and hydraulics of your brakes are in good order and you get that Hydravac working, be careful when you step on the brakes. I have one on a 1 ton '58 Chev flatbed and those brakes are fantastic!

Kinda. It was a factory/dealer option, but that is not where the dealer would have installed it. It would have been on the drivers fender skirt.

How did these things work ? Are they a worthwhile addition?

I think they work very well. You can get 800-1000 lbs of assist depending on the model. I have one on my wagon with 4 wheel discs. Best brakes of ANY vehicle I have ever owned or driven.

Somewhat like a vacuum booster in more modern cars. Manifold vacuum pulls on a big diaphragm in the hydrovac. When you step on the brake pedal hydraulic pressure trips the hydrovac and sends high pressure brake pressure to the wheel cylinders. Some had one fluid circuit to the master, some had two circuits: master to hydrovac and then hydrovac to wheel cylinders. Its basically the first go at modern power brakes.

I have looked and searched for a photo or anything actually showing where it was mounted from Willys with no success. I remember you saying you saw one once but no pics. Can you shed anymore light on where exactly it was mounted on that fender skirt, because that area is already pretty crowded vs the passenger side. Below the battery is a possibility but with battery acid drips, corrosion, etc, that seems like a bad spot. I did buy one and plan to add it on Wilbur when I get to that stage, along with the Bendix self adjusting (already purchased) on all 4 corners.

I had one on my 61 2wd wagon and it was mounted on the passenger fender well in front of the heater exchanger.
First car I ever drove so can’t say how it compared. Too many years ago. Although I don’t remember the breaks being a problem.

To me, the passenger side makes sense with the exception, it’s a long way from the master so lots of plumbing.
