What's missing from your shot IcePack, is the little spring that pulls the pawls together, so when you operate the brake after re-assembly if there's play the serrations on the pawl take up this slack but can't release back when you let off the brake - essentially taking up the shoe to drum gap and give a nice short hard pedal 'feel'
You can just see the spring here (opposite side under the Y47 mark)
