There are two different types of release bearing Audi A3 :
- Pulled release bearing
- Hydraulic release bearing
It is the most unconventional of the two types of release bearing . This one, contrary to 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.
