If you're talking about the spring retention flange on the brake centre bolt, it's not meant to be removed. Consider it integral to the centre bolt. In some cases it's an separate piece that is pressed onto the bolt using an interference fit but in other cases it's part of the billet that is forged or turned to manufacture the centre bolt.
It doesn't look there is anything missing from the diagram.
