Clutch Hydraulics-Common Failures

COMMON REASONS FOR FAILURE

The most common issue for clutch master and slave cylinders is contamination of the hydraulic fluid or even the wrong type of hydraulic fluid being used. The smallest drop of contaminant, such as engine oil, gearbox oil, washer fluid or antifreeze can cause the rubber seals within the cylinder to swell up overtime. When this happens, the cylinder can no longer work properly and can seize.  Often, the contaminant is introduced into the hydraulic system when using the same funnel or pouring container, between different types of fluids.

When replacing CSCs, the most common cause for failure is not using the correct bleeding procedure and therefore special care must be taken by the installer to follow the correct process.

TECHNOLOGY AND FUNCTIONALITY

Clutch hydraulics are an integral part of the modern vehicles stop-start system and over years, FTE has developed innovative solutions, in particular hydraulic sensor technology, in conjunction with vehicle manufacturers, to drive efficiency and economy demanded by the vehicle driver today. A recent technology delivered by FTE is the double clutch concentric slave cylinder which is used in the new Audi A6 gearbox.  The system helps facilitate seamless gear changes and allows for the traditional clutch pedal to be removed, therefore enhancing driver comfort. This is expected to be introduced by FTE in the aftermarket in the next couple of years – so is one to watch out for.
