Product Description
Spring Brake Valve
Features & Benefits
- Works between the foot valve and the spring brake chambers
- Appears on many dual-circuit air brake systems as an SR-series valve
- Controlled spring brake application helps the driver stop smoothly after a circuit loss
- SR-5 design sits between the foot valve and spring brakes
Bendix SR-5 Spring Brake Valve
Control spring brake application after a service circuit failure with the Bendix SR-5 Spring Brake Valve. If one service circuit loses pressure, the SR-5 lets the driver apply the spring brakes gradually through the brake pedal. That makes the Bendix K033221 part of the vehicle's backup braking, so a failed valve is a safety concern even when daily braking feels normal. Testing it as the vehicle maker directs after installation confirms the backup function works.
