I am not sure why the Huck design is inferior. They are set up very similar to a modern air brake with the bottom of each shoe anchored on a pivot pin.
They are sensitive to mis-adjustment because a lot of people do not understand how to adjust them. Each side of the wheel cylinder has to be turned clockwise as you look at the front of the shoe. That means that to adjust one brake, each side of the wheel cylinder is turned opposite each other to bring each shoe toward the drum. You do have to be careful but it is not rocket science..
Kanter Auto Parts has the wheel cylinders, I bought some recently..
Yes, the parts are more expensive. But, how often are you going to rebuild your brakes in order to recoup the 400 dollar Bendix swap cost ? The way I drive my truck I am sure my brakes will last ten years..
If you want to change them, change them. Just be sure you are an informed consumer before you make the change...
