Bleeding air from the hydraulic drive (Chevrolet Aveo T250)

Bleed any air from the hydraulic system that was introduced when the lines were disconnected for repair. The fluid level in the clutch/brake reservoir should be kept at or above the minimum level while bleeding air.

1. Attach a flexible transparent tube to the bleeder valve. Place the other end of the hose in a glass container half filled with brake fluid.



2. Slowly pump the clutch pedal several times.

3. While pressing the pedal, loosen the air bleed screw and wait until the liquid starts to flow out. Close the bleed valve.

4. Repeat step 3 until there are no bubbles in the liquid flowing through the tube.

Fill the reservoir with fluid to the maximum level.

Note: If removing air in the above manner does not produce results, air can be forced out of the system by pumping clean liquid through the bleed valve, i.e. "from the bottom up". To do this, you can use a syringe and an elastic tube, which should be tightly connected to the bleed valve and the syringe.

In this case, during the process of removing air, excess liquid should be removed from the expansion tank.
