Brake Camshaft
Bendix

Engineered for clockwise rotation in high‑duty drum brake actuation paths, this longer shaft measures 18.87 inches in active length and uses a 1.50 inch spline with 28 teeth for a secure drive interface. The extended form supports deeper actuation strokes, enabling greater leverage at the shoe interface and improved braking torque without increasing package size. The 28‑spline engagement ensures strong mating with drive gears and cam plates, contributing to reduced wear and consistent actuation across cycles. Compatibility with standard Bendix 28‑spline hubs enables straightforward replacement in mixed fleets, minimizing downtime and inventory complexity. VMRS code 013-001-031 situates this part within the brake actuation subsystem for accurate work order coding and part tracking. In practical use, this component supports reliable shoe application timing and even wear patterns across a wide range of temperatures and loads, making it suitable for heavy‑duty highway, vocational, and off‑road fleets when paired with appropriate shoes and anchor hardware.
