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 (based 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 distinct variants of release bearing Renault Laguna :
- Pulled release bearing
- Hydraulic release bearing
It is the most unconventional of the two variants of release bearing . This one, compared with the hydraulic form, is operated by a mechanical pulling system that will release the clutch disc. In this case, the release bearing must be mechanically fixed to the mechanism.
The hydraulic release bearing, although more technical, is the type most used in contemporary vehicles. It is however more complicated than the pulled release bearing. Indeed, it will be composed of a hydraulic tube that will receive the pressure right from the clutch pedal.
