There are two different variants of release bearing Toyota Corolla :
- 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 situation, the release bearing must be mechanically fixed to the mechanism.
