Pressure Booster

Pressure Booster — Pedal Comfort in the Clutch System

The pressure booster is a component that forms part of the clutch system's subassembly in heavy commercial vehicles, reducing the force the driver applies to the clutch pedal and assisting the movement of the pressure foot. Since clutch pressure force is quite high, especially in loaded trucks and buses, transmitting this force by human foot alone becomes tiring and, over time, physically demanding. The pressure booster significantly reduces pedal force by providing air or hydraulic assistance, making clutch operation smoother and more controlled.

The product range includes complete pressure booster assemblies as well as the many subparts and consumables that make up this component. To make the correct selection, it is necessary to identify the part suited to the vehicle's clutch system and operating conditions.

• Complete pressure booster units
• Cylinder body, piston and gasket sets
• Connection elements, hose and fitting sets
• Repair kits and seal sets

The pressure booster is a part that shows general compatibility across major truck and bus brands, but may vary by vehicle model and clutch system. Choosing an incorrect or incompatible part can lead to pedal stiffening, premature wear of the clutch coupling, or difficulty shifting gears. For this reason, correctly identifying the pressure booster suited to the vehicle's clutch assembly is important both for driving comfort and for the system's service life. Regular inspection and timely replacement ensure the clutch system works in harmony with its other components. Browse the product options below to find the right pressure booster for your vehicle.

Frequently Asked Questions

What is a pressure booster? It is a component that reduces the force applied to the clutch pedal, operates with air or hydraulic assistance, and forms part of the clutch system's subassembly.

What are the symptoms of a pressure booster failure? Excessive stiffening of the clutch pedal, a sudden sense of play when pressing the pedal, or difficulty shifting gears are the most common symptoms of failure.

When should the pressure booster be replaced? Replacement may be needed when there is a noticeable increase in pedal stiffness, an air or oil leak appears, or a delay in clutch response is noticed.

How is the correct pressure booster selected? The correct selection is made by choosing a part with dimensions and connection structure suited to the vehicle's clutch assembly and current system type.

How does the pressure booster relate to other parts of the clutch system? Since it works by lightening the force coming from the pressure plate and clutch coupling, it must perform compatibly and in sync with these components.

How is the pressure booster maintained? The sealing of connection points, the integrity of the air or hydraulic line, and the moving parts must be regularly checked.

Can the clutch be used without a pressure booster? Although the system will still work, pedal force increases noticeably, which reduces driver comfort and can cause fatigue over the long term.
