This Bendix drum brake layout became an industry standard. Pre- and post-war trucks use Bendix-, Chrysler-, Lockheed-, Wagner-, or Huck-style brakes. By the end of the '50s, the Bendix design dominated American light trucks. Self-energizing Bendix duo-servo brakes have a dual-piston wheel cylinder, a single (top) anchor pin and an adjuster link between the shoes. Bendix duo-servo brakes with self-adjusting mechanisms are found on disc front/rear drum systems of modern trucks.
