This exhaust brake valve controls the flow of exhaust gases to actuate the engine's exhaust brake system, aiding in deceleration and reducing wear on service brakes. It is constructed from high-quality materials to withstand high temperatures and pressures, ensuring reliable operation unlike a worn valve that may stick or leak. Operators may notice a lack of engine braking effect, or the exhaust brake warning light illuminating on the dashboard when this valve malfunctions.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first symptom of a failing exhaust brake valve is a reduced or absent engine braking effect when the system is activated. If ignored, the valve may become completely stuck, either open or closed, potentially affecting engine performance or causing the exhaust brake warning light to remain illuminated. A stuck-closed valve can lead to overheating of the exhaust system components.
Ensure the electrical connector is clean and securely attached before installing the new valve. Avoid applying excessive force when tightening the mounting bolts, as this can damage the valve body.
Inspect the exhaust brake actuator and linkage for proper operation and check the exhaust system for leaks.
