That technique looks good on paper but in reality doesn't work very well on any drum brake I've ever seen. The best way to adjust them is by hand.

In the past few years, auto adjusters on trailer brakes have come into being, Dexter among the first. They seem to work well enough, once they are initially (manually) adjusted to get 'em close.

If you have one magnet surface that's flat, then a new magnet is going to engage and pull better than a new magnet would with a drum with a deeply grooved magnet surface. When I was dragging my brake drum all over town trying to find a replacement, I had a technician look at it and he said it was too deeply grooved to use as-is. The others were all about the same so I ended up getting three of them machined on a flywheel surface grinder. The fourth one is a new one so I wouldn't have expected to get equal braking performance out of all four tires if I had installed them as-is instead of having them machined.
