1. Attach a flexible transparent tube to the bleed valve. Place the other end of the hose in a glass container half full of brake fluid.
2. Slowly pump the clutch pedal several times.
3. While depressing the pedal, loosen the air bleed screw and wait until fluid 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 tank with liquid to the maximum level.
Note: if removing air in this way does not work, air can be expelled from the system by pumping clean fluid through the bleed valve, i.e. «down up». To do this, you can use a syringe and an elastic tube, which must be tightly connected to the pumping valve and to the syringe.
In this case, in the process of removing air, excess liquid should be taken from the expansion tank.
