There are two distinct types of release bearing Nissan Micra :
- Pulled release bearing
- Hydraulic release bearing
It is the most unconventional of the two types of release bearing . This one, unlike the hydraulic type, 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 complicated, is the form most used in modern vehicles. It is however more complicated than the pulled release bearing. In fact, it will be composed of a hydraulic tube that will receive the pressure straight from the clutch pedal.
