Abstract: A brake shoe for a drum brake is provided that improves the direction of the brake actuating forces to reduce stress, improve efficiency and permit thicker brake linings. The brake shoe has a web having first and second ends with the first end configured for pivotally coupling to an associated brake spider. A brake table is supported on the web. The second end of the web is configured to engage an associated cam follower that causes the brake shoe to move between positions of engagement and disengagement with an associated braking surface at either of first and second radially offset positions on the second end of the web such that the cam followers can engage two brake shoes in the brake at offset positions and improve the direction of the force vectors.
