46 still uses huck brakes. Bendix brakes are a little bit more efficient than the Huck brakes. Regardless either system will work better with a power booster.

My preference was upgrade to go with 4 wheel disc brakes on my 1940 3/4 ton. 4 wheel drum brake systems without automatic adjusters are SCARRY! I can't tell you how many times the uneven grabbing of the drum brakes caused me to spin out of control in my 1st truck. It put me on the driver's side 2 wheels once while I was on the freeway... an event that I would not want to duplicate.
