Function of the release bearing on Nissan Sentra

It is controlled by the clutch pedal and then by the release fork, which, when it is activated, will press on the clutch and release the gearbox from engine rotation for you allow you to shift gears on your Nissan Sentra.
Objective of release bearing Nissan Sentra
Let’s now look at the technical side, the release bearing is composed of two parts, 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 sort of release bearing Nissan Sentra :
- Pulled release bearing
- Hydraulic release bearing
It is the most unconventional of the two sort of release bearing . This one, as opposed to the hydraulic type, 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 complicated, is the kind most used in contemporary cars. 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.

Indeed, this noise often comes from the broken fork that no longer allows the system to run normally.
