9735000470 Quick Release Valve — Volvo FMX FE Series trucks — FH400

This is a quick release valve, a critical component in the air brake system that rapidly exhausts air from the brake chambers. It ensures faster brake application and release, improving vehicle responsiveness and safety compared to a worn valve that may stick or leak. Operators may notice delayed brake response, longer stopping distances, or a hissing sound from the air system when this part fails.

Installation & Application Notes

Always replace brakes in axle sets. Bed-in new brake pads with 8–10 moderate stops from 40 km/h. Check disc runout with a dial gauge — maximum 0.1 mm. Inspect caliper slides and pistons when replacing pads.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing quick release valve is often a noticeable delay in brake application or release. If ignored, this can lead to inconsistent braking performance, potentially causing the vehicle to drift or pull during stops. The ultimate risk is extended stopping distances, increasing the likelihood of an accident.

Installation Tip

Ensure all air lines are clean and free of debris before connecting them to the new valve to prevent internal contamination. Avoid overtightening the valve body, which can crack the housing or strip the threads.

Service Note

Inspect all air brake system hoses and fittings for leaks or damage when replacing the quick release valve.
