  • Pull style double diaphragm spring brake actuator
    Patent number: 9701294
    Abstract: A spring-type brake actuator for a vehicle brake such as a pneumatically-actuated brake is provided, in which the actuator's operating rod is pulled toward the actuator to apply the brake. The actuator's parking brake release piston is located closer to the brake than the service brake piston, and the parking brake power spring is positioned between the mounting end of the actuator and the parking brake piston such that when parking brake release pressure is removed from the parking brake release chamber the parking brake piston biases the operating rod in the brake application direction, drawing the operating rod further into the actuator.
