There are two different variants of release bearing Nissan Xterra :
- Pulled release bearing
- Hydraulic release bearing
It is the most unconventional of the two variants of release bearing . This one, compared with the hydraulic version, 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 complex, is the form most used in modern vehicles. It is however more elaborate than the pulled release bearing. Indeed, it will be composed of a hydraulic tube that will receive the pressure directly from the clutch pedal.
