There are two different types of release bearing Toyota RAV4 :
- Pulled release bearing
- Hydraulic release bearing
It is the most unconventional of the two types of release bearing . This one, unlike 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 complex, is the version most used in modern cars. 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 right from the clutch pedal.
