Clutch release bearing (Opel Vectra B)

The clutch release bearing is pressed by the central clutch release module to the tips of the disc spring of the pressure plate when the clutch pedal is pressed. As a result, the clutch is unloaded. This thrust bearing is not subject to maintenance. If it is faulty, it attracts attention with grinding noises when the clutch is pressed. Because of this, it does not need to be replaced immediately. This work can be postponed until the next clutch replacement.

Removal the central clutch release module with release bearing

Remove the gearbox.

Unscrew the pressure line from the central clutch release module.

Unscrew the three mounting bolts of the central clutch release module and remove the module together with the gearbox housing.

Remove the O-ring underneath and insert a new one, lubricated with oil.

The central release module and release bearing are closely related. If there is no tightness or damage, the central release module must be replaced as a whole.

Tighten the central clutch release module to 5 Nm.

Tighten the discharge line to 14 Nm.

After assembly, fill and bleed the hydraulic clutch system.

Bleeding the Clutch Hydraulics

Fill the brake fluid expansion tank with fresh fluid.

When pumping, make sure to add fresh fluid in a timely manner, before its level drops. Otherwise, air will be sucked into the system again, and the work will be in vain.

Remove the dust cap from the bleeder valve on the transmission and slide a clear hose over the cleaned valve.



Place the free end of the hose into a container partially filled with brake fluid.

Open the bleed valve half a turn.

Have your assistant slowly press and release the gas pedal until no air bubbles are visible in the hose.

When there are no more air bubbles, the assistant should hold the clutch pedal in the lowest position, and at this time you close the bleed valve. Tighten carefully, otherwise the valve will be torn off! (9 Nm).
