Air is removed from the system if it has been opened. The system should be filled only with fresh and clean liquid. You cannot use the leaked liquid for this purpose.
Brake fluid is poisonous and has a destructive effect on paintwork. Therefore, the liquid should be handled with care.
If there is a damping cylinder in the system, air is released from it before air is released from the working cylinder.

2. Open the reservoir to check the fluid level. If necessary, add fluid up to the "Max" mark.
3. Remove the protective cap from the air bleed nipple on the top of the gearbox.
4. Place a transparent hose on the fitting and lower the other end into a transparent container. Pour some liquid into the vessel. Make sure that the end of the hose is always below the liquid level in the container.
5. Press the clutch pedal evenly. At the end of the pedal stroke, press down hard on the pedal. Open the air bleed nipple. Once the clutch pedal is pressed to the floor, close the bleeder valve.
6. Repeat the described process 10-15 times. In this case, it is necessary to monitor the liquid level in the tank, adding liquid. As soon as the liquid flowing out of the hose does not contain air bubbles (bubbles no longer rise up in the vessel), the air has been removed from the system. Tighten the fitting to a torque of 9 Nm.
7. Check the fluid level in the reservoir. Check the operation of the clutch as described in Section Checking the clutch without removing it.
Note: Brake fluids from different manufacturers are available. However, it is necessary to stick to the fluid recommended by Opel. This fluid mixes well with the fluid still in the system.
