Action of release bearing Mercedes Gla
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 (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 different types of release bearing Mercedes Gla :
- Pulled release bearing
- Hydraulic release bearing
It is the most unconventional of the two types of release bearing . This one, contrary to 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 complicated, is the kind most used in contemporary automobiles. It is however more sophisticated than the pulled release bearing. In fact, it will be composed of a hydraulic tube that will receive the pressure directly from the clutch pedal.
