Technical support 7.1 Replacement of the hydraulic components The actuation system is composed of a mechanical part, which is the pedal, the firewall and the over- center spring. The hydraulic system consists of a transmitter (clutch master cylinder), a hose with or without a damper and a receiver (clutch release cylinder or concentric slave cylinder). It is important to realize that the performance of the hydraulic system is also linked to the mechanical part. During each clutch replacement or once an actuation problem is detected, it is important to check all of the components in the transmission line, from the pedal to the gearbox. This will avoid unnecessary replacement of expensive components and unexpected labor costs. However, many clutch failures are also linked to poor functioning of the hydraulic actuation system.
