Clutch control

The force we apply when depressing the clutch pedal must be transmitted to the central clutch release module. In the Vectra, this is done hydraulically, as in the brakes. When you press the clutch pedal, the piston in the slave cylinder (on the clutch pedal) displaces a certain amount of fluid and presses it against the central clutch release module with an integrated master cylinder (in the gearbox). There, the piston moves slightly out of the release module and drives the release bearing located directly in the release device.

Do I need to disengage the clutch when stopping at an intersection?

A very common habit is to wait at a red traffic light, put the car in 1st gear and fully depress the clutch. Some are afraid that they will not be able to immediately turn on the transmission at the green light.



Even if there is no direct or immediately measurable damage, the disengaged clutch still creates a negative load on the central clutch release module (with clutch release bearing) and thus contributes to its wear. The more often and longer this happens at the passage of numerous traffic lights, the sooner the bearing of the central clutch release module will wear out.
