1956 brakes
I have a f600 with a small stock master cylinder under the drivers side floorboard . It is showing signs of leaking. I have bigger then stock front suspension and brakes , I also have a lot of mass on the truck with a double frame and a tag axle with all the rear suspension . My question is can I put a bigger master cylinder in the stock location ,should I put in a booster on it , can I put one on the firewall?
What did you do to upgrade your brakes?
I do have air brakes on the tag but I do not know if they work!

Putting in a "bigger" MC (bigger how?) will not improve the brakes. The MC size needs to be matched to the wheel cylinder size to work properly, single circuit drum brakes don't require a physically large MC. I'm not very familiar with the original size brakes on a big job F600, but the ones in your picture don't look oversized or having been changed.

All single circuit. (I have never liked single circuit brakes)
Looking at your pictures, it appears that you have upper and lower wheel cyls in the front and you probably have double actuators in the back.
Yes, you can install a vacuum assisted inline booster. Ford used single circuit, vacuum boosted brake systems well into the late 60's and/or early 70's.
I intend to convert my brakes to a double circuit hydraulically boosted master cylinder. (the later double circuit F-600's used 2 vacuum boosters)
It's important that you use a master cyl that has the same diameter piston and stroke so you can provide similar pedal movement and feel. Even if you do, you may have to install a proportioning valve to make it work correctly.
It also has to work when you lose either vacuum or hydraulic power for the booster. so the piston cannot be too big or you won't have enough leg strength to stop!
