Abstract
A brake shoe for a drum brake includes a unitary body defining a brake table and one or more webs supporting the brake table. Each web has first and second ends. The first end is configured for pivotally coupling to an associated brake spider of the drum brake and the second end is configured to respond to a force applied by an actuator that causes the brake shoe to move between positions of engagement and disengagement with an associated braking surface. The unitary body further defines one or more supports extending between the two webs and/or between one of the webs and the brake table. In some embodiments, the supports comprise vibration dampers configured to deflect from an unloaded position to a loaded position in the presence of a load and to return to the unloaded position in the absence of the load.
