Restore fail-safe parking and emergency braking with the Bendix Spring Brake, pairing a service chamber with a spring-actuated section built for S-cam brakes. The Bendix NT3030STD-78TC bolts to the same spider pattern this S-cam axle position uses, so brake geometry lines up without modification. The spring section applies the brakes mechanically the instant air pressure is lost, whether from setting the parking brake or an actual air-supply failure, while the service section handles normal stops. The replacement restores both service and parking functions without changing the axle's established S-cam geometry.
