I'm pretty sure the brake lines on my 54 6400 are quarter inch. Can anyone confirm this?

you will have a larger brakeline size on the front and the line will split in the rear to a smaller size. what this does is even out the back pressure in the lines and will not require a control valve. it is 1/4 rear and a little bigger for the other lines

According to the shop manual, all the lines on 3/4 ton and larger are 1/4"/

'56 duece has 1/4" from stem to stern. With the dump conversion the rear slaves draw a lot more fliud than the front.

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion!
