Function of release bearing Citroen C4 Cactus
Let’s now look at the technical side, the release bearing is composed of two units, a first fixed part that slides only when the stop is pulled, or pushed (depending on its type) and finally a rotating part that is composed of a bearing that will allow it to stay in contact with the mechanism and follow its rotation.
There are two different variants of release bearing Citroen C4 Cactus :
- Pulled release bearing
- Hydraulic release bearing
It is the most unconventional of the two variants of release bearing . This one, as opposed to the hydraulic form, is operated by a mechanical pulling system that will release the clutch disc. In this situation, the release bearing must be mechanically fixed to the mechanism.
The hydraulic release bearing, although more technical, is the version most used in contemporary vehicles. It is however more complex than the pulled release bearing. Indeed, it will be composed of a hydraulic tube that will receive the pressure right from the clutch pedal.
