This clutch booster cylinder is a vital pneumatic hydraulic component of the heavy truck clutch operating system. It amplifies the force from the clutch master cylinder to assist clutch separation and engagement, reducing the driver’s pedal effort for smoother operation. Adopting high-strength cast housing and imported sealing components, it delivers excellent pressure resistance and leak-proof performance. It can work reliably under high vibration and fluctuating temperature conditions on long-distance transport routes. Every clutch booster undergoes air tightness and pressure testing before delivery. It solves common faults such as heavy clutch pedal, slow clutch disengagement and oil leakage, acting as an indispensable replacement spare part for heavy truck clutch system repair.
