OOPS! Huck brakes are a little more complicated, since eachshoe adjusts individually. The same basic concept applies, however. Each shoe needs to contact the drum firmly, then back off enough to let the wheel turn without dragging excessively. If you don't get a good contact with the drum first, the wheel cylinders have to take up the slack, and you end up with a low pedal.
