EMPTY AND LOAD BRAKE SYSTEM ABSTRACT OF THE DISCLOSURE An empty and load brake device for a railroad vehicle air brake system includes an air pressure source, a control valve, a proportional valve and a brake cylinder all connected in series. A load sensor valve is in fluid communication with the line between the proportional valve and the brake cylinder. If the sensor valve senses an empty load condition, it actuates the proportional valve to de- crease the air pressure supplied to the brake cylinder. The load sensor valve has a rock and roll spring which dampens movement caused by rough track conditions, thereby preventing erroneous indications of either an empty or loaded car. - 1 -
