DD-3 Brake Actuators

 

DD-3 brake actuators are dual-diaphragm, air-operated chambers engineered for heavy-duty applications requiring service, emergency, and parking brake functions. Unlike standard spring brakes, the DD-3 uses a mechanical push rod lock system that engages automatically when air pressure is lost, ensuring the brakes remain applied. With a unique roller-and-wedge locking mechanism activated through a dedicated lock port, the DD-3 provides fail-safe parking and emergency brake retention. Commonly used on buses, specialty vehicles, and military equipment, DD-3 actuators deliver dependable performance in critical stopping scenarios.
