Abstract
A duo servo drum brake shoe anchor having a T-shaped configuration in which the inner recess corner surfaces define a pocket on each side, each of which receives a rounded end of one of the shoes in force transmittable engagement. The crossbar part of the anchor is located on one end of the keystone-shaped main body part of the anchor. The main body part has slanted sides which contract the tendency of the secondary shoe end, for example when forward braking is in process, to move outwardly in a wedging action, and the crossbar part lower sides forming part of the pockets prevent the shoe end in the pocket from moving outwardly toward the drum being braked.
