This is a floating self energizing system were one shoe pushes the other into the drum and the shoe can find its own centre The Model A to 34 backing plate has a track that the shoe roller pin rides on restricting down ward movement this develops a groove that the shoe pin drops into ,the stamping plate does away with this so the shoe can move up or down ,At the adjuster end instead of a cone you now have a floating wedge so one shoe pushes the other ,its a kind of self adjustment .when fitting the top ,if the shoe links are repoped you may need to polish the under side of them for free movement ,that's in the instructions ,
