Spider and Pin Assembly
Bendix

A spider-and-pin assembly that provides a precise, stable interface between the actuation shaft and the brake shoes. The assembly distributes load evenly across the anchor points, helping to maintain concentric shoe movement and consistent contact with the drum or rotor. Its bolt-circle diameter of 8.25 inches ensures proper alignment with the hub pattern, reducing the risk of misalignment-induced wear or binding during high-cycle operation. The component is integral to predictable retraction and application sequences, minimizing noise and vibration while preserving even wear across the shoe face. VMRS code 013-001-088 places it within the mechanical actuation subgroup, and category 41390 contains related drive components for drum and disc brake systems. Cross references are not listed, so technicians should verify compatibility with the target drum brake model and anchor hardware before replacement. In service, a correctly matched spider and pin assembly supports reliable, quiet operation and longer subsystem life in challenging, high-mileage fleets.
