The Huck brake has the shoe adjusters on the wheel cylinders, one for each shoe. Bendix brakes have self-centering shoes, with a single adjuster between them at the bottom.
If you're not getting equal brake wear at all the wheels, something is preventing the shoes from applyling pressure to the drum on the wheel with little, or no wear. It's usually a collapsed flex line, if one of the front brakes is not wearing normally. Pressure builds up upstream of the flex line, and allows the other brakes to apply, with little, or no brake effect on the wheel downstream of the bad line. This also makes the front end pull toward the wheel that's braking normally. To check for a bad line, remove the drums, and have someone GENTLY apply pressure to the brake pedal. The shoes should move with only a slight pressure applied, and retract when the pedal is released. Don't overdo it, and blow the cups and pistons out of the cylinders! Slow, or no movement of the shoes, and slow retraction, indicates there's a restriction in the hydraulic circuit to the shoes that aren't moving properly, or sticky or frozen wheel cylinder pistons. Repair as necessary.
