1.Combined Service & Parking Brake
Integrates a service chamber and a spring (parking/emergency) chamber in one unit, providing both daily braking and parking protection with fewer components.
2.Strong Braking Force for Heavy Loads
Dual-chamber design delivers higher output force, ensuring stable and powerful braking for heavy-duty trailers, long-distance transport, and steep terrain.
3.Automatic Emergency Braking (Spring Brake Safety)
If air pressure drops or fails, the built-in heavy spring automatically applies the brake, preventing vehicle roll-away and improving overall safety.
4.Durable Construction & Long Service Life
Reinforced steel housing, corrosion-resistant coating, and high-strength diaphragm ensure reliable performance under harsh road conditions and extended operation cycles.
