The Meritor Air Brake Spider forms the structural mounting point that holds drum brake components in position along the axle. Brake shoes, camshafts, and return springs attach to this component so the drum brake assembly stays aligned during operation. It anchors these braking elements to the axle housing while allowing the camshaft to spread the brake shoes against the drum surface. This structure supports the mechanical relationship between moving brake components and the fixed axle housing. The Meritor A3211P3448 provides the mounting framework that keeps drum brake components arranged around the axle.
