My comment on the "clicks" thing was actually referring to the manual although I don't know how many clicks they talked about. I have a 1938 Master and a 1951 GMC 1 Ton, both with the original style Huck brakes. Non of the drums give a perfectly even drag even after turning the drums. All it takes is a difference of a thou or so and the drums don't mount that accurately to the hubs. My brakes work really well with no vibration. The design of the original system takes into account the pedal leverage ratio, the master cylinder bore and the wheel cylinder bores, just among a few of the factors. You might want to check the bore size of the master as compared to the original.
