Hi Martin,
the brake aligning tool is used to check concentricity of the shoes in relation to the axle.The tool has a vee clamp arrangement that clamps onto the axle and you set the gauge to a point anywhere and spin it slowly checking various points around the shoe diameter.There is also another part to the kit that measures the drum and compares it to the shoe diameter you have set.It was made in the USA by Shepard Thomason Co.Not sure what it is called but i use it every time i set up brakes with and offset cam arrangement ie my old Mack and CMP.It turned out when the lower cams were in their neutral position the shoes were perfectly concentric on the Chev.
