The Double Diaphragm brake chamber is a high-performance braking component mounted on a vehicle's axle; it connects to the slack adjuster via a clevis, thereby directly engaging with the vehicle's braking system. During braking, compressed air enters the upper and lower chambers through ports 11 or 12, actuating the diaphragm; this drives the pushrod to engage the slack adjuster, thereby achieving precise and reliable braking. Easy to install and compatible with a wide range of vehicle models, this product offers diverse braking solutions for light-duty trucks, heavy-duty trucks, and specialized vehicles.
The DD brake chamber offers various connection methods to meet diverse requirements: models utilizing a clamp-band connection allow users to easily replace individual components, effectively reducing maintenance costs; conversely, models featuring a "Sealed" connection simplify the structural design while ensuring safety, thereby enhancing maintenance efficiency. The product also offers a choice of stroke lengths, which can be distinguished by the shape of the air port on the aluminum center section: a square air port indicates a long-stroke configuration, suitable for heavy-duty trucks subject to continuous high-load operation; a circular air port indicates a standard-stroke configuration, suitable for the majority of vehicle models.
The aluminum center section of the DD brake chamber is equipped with a caging bolt, allowing for easy locking during main spring replacement—a feature that significantly enhances both the convenience and safety of installation and maintenance procedures. Furthermore, the company offers various surface finish options to satisfy diverse customer preferences regarding product aesthetics. Thanks to its precision engineering, versatile configurations, and operational convenience, the DD brake chamber delivers stable and reliable braking performance across a wide spectrum of operating conditions, serving as a robust safeguard for vehicle safety.
