I 1952 6400 with Huck brakes and Hydrovac unit. Whoever had it first took out all the brake plumbing. I know how to make brake lines, but does anyone have a diagram of how to plumb it all with the hydrovac in it? Also, how to test the hydrovac would be helpful. Once I get the brakes going I can drive it around instead of towing it to move it.
