Another thing that it took me a couple years to figure out with Huck brakes is you have to adjust both shoes separately, unlike Bendix brakes. Run one shoe out until it drags, then back it off and do the other side the same way. I used to have to pump my brakes also, with a good strong pedal after pumping. It just took too much fluid movement to get the shoes in contact with the drums, requiring the extra pump.
