Abstract
The present invention encompasses a truck mounted brake system for double axle wheel trucks with pneumatic means operable through multiple levers to move the brake beams relative to each other. The lever system includes a double acting slack adjuster responsive to load changes to vary the braking force. Different load weights on the bolster causes it to assume different vertical positions relative to the side frames and the slack adjuster to vary in length so that uniform pressure to the pneumatic means produces higher brake pressure to the wheels of fully loaded cars and lower brake pressures to partially loaded and unloaded cars.
