Small shoe facing front and big shoe facing rear. When you understand how Bendix brakes work, you can see that reversing that can lead to grabby/sensitive braking.
He had the emergency brake cable too tight. It is supposed to have just a bit of slack in it when it's not engaged, right? I guess he got the shoes on right, but I drove 40 miles and the shoe pads are half gone with the surface a bit shiny. The driver's side was adjusted way out, like 3 complete spins on the adjuster wheel. The passenger side was maybe 1/4 turn from 0. It supposedly had brand new shoes 40 miles ago, now they are just a hair over 3/16ths.
