Pneumatic Clutch Booster

Booster Systems

Booster systems are used in many applications They are used to boost output on: Clutches Brakes Steering.

Clutch Boosters

Are used on heavy duty trucks and buses to reduce excessive clutch pedal loads and effort.

Pedal Effort

High clutch pedal loads no longer need to be tolerated. This is particularly true as more drivers are steeping into vehicles with 600 plus horsepower.

High Horsepower

High Horsepower + large torque demand introduced into the clutch demands equally large clutches. Without a clutch booster, short throw pedals are impossible.


With a clutch booster integrated into the system, light pedal force can be had with a short clutch pedal throw.


This improves driver performance from a fatigue viewpoint as well as a quality of driving factor. Driving control of any vehicle whether it’s a sports car or road train is always improved when all controls are balanced.

Pneumatic Clutch Booster System

This system was introduced by the Cablecraft Motion Controls USA in 1994 and is designed to reduce the clutch pedal effort.

Main components are the Load Sensor Regulator and Booster Cylinder. All components are corrosion resistant. No lubrication or maintenance is required when the system is properly used for recommended applications.

Pneumatic Clutch Booster

Pneumatic Clutch Booster System Operation

The power booster is a pneumatic force sensitive linear servo device. Input / output force ratio is independent of stroke position and may varied to suit the application. Initial input force required to start magnification of the output force can also be specified. Various stroke lengths are available.

The Booster cylinder receives controlled air from the Load Sensor Regulator. Separation of these two functions improves the design options when fitting system into new or existing vehicles

What is reasonable pedal force?

The best way to answer that is to look at the forces required to operate the brake, throttle and clutch. Effort for all controls should be balanced without any function requiring noticeably greater effort than the other.

Why use a Booster System ?

  • Reduces operator fatigue
  • Fail Safe Increases machine life and dependability
  • Reduces manual loads on lever pedal
  • Easy to install
  • Can be used with cable or rod linkage clutch systems
