p.j., if everything is new and the lines are completely bleed of air and the shoes are adjusted up properly and the master cylinder plunger has the proper clearance and all the slop is taken out of the pedal linkage and is freshly lubed (stops to takes a breath). You should have about 3/4" free play in the pedal before you feel the pushrod make contact with the piston in the master cylinder. From there on it's just non-compressible fluid in the lines and wheel cylinders pushing the shoes out to contact the drums.
Depending on how much clearance you have given the shoes to the drum, you will end up with one to two inches of pedal movement to make a normal stop. As the shoes wear down this will increase and a break shoe adjustment should bring it back up to the short stroke again.
Depending on the shoe adjustment you may get three to four inches in a panic stop that locks the wheels up because of flex in all the components.
Unlike the single adjustment of the Bendix brakes, each shoe on the Huck brakes has to be adjusted up with even clearance to the drum. It is dificult to get the proper feel with all new wheel cylinders and next to impossable with old rusty adjusters.
