An empty load device for railroad cars in which the fulcrum employed to transmit braking forces to the car trunk, for instance, the brake rigging cylinder lever pivot pin, is mounted relative to the cylinder lever for shifting movement longitudinally thereof, and a cable is connected between the pivot pin and a movable member that is moved by means for sensing the load weight changes on the car to shift the pivot pin as required to maintain braking forces applied to the car wheels below that which will cause locking of the wheels.
