When bleeding, add only clean DOT 3 fluid recommended by the manufacturer.
Caution! Never reuse fluid that has leaked from the hydraulic clutch drive.
Please note: Brake fluid is hygroscopic, meaning it absorbs moisture from the air. Therefore, it is not recommended to use liquid stored in an open container for a long time.
If fluid constantly leaks from the hydraulic drive or air enters the hydraulic system, determine the cause and location of the leak and repair the damage.
Remove air from the hydraulic clutch drive as follows: (during bleeding, make sure that the brake fluid level does not fall below the middle of the brake system reservoir):
Remove the protective cap from the bleed nipple on the clutch slave cylinder and clean the nipple.
Place one end of the transparent hose on the bleed nipple and lower the other end of the hose into a glass container filled with brake fluid to a depth of 5–7 cm.
The assistant should press the clutch pedal and, while the pedal is pressed, unscrew the bleeder screw by half a turn.
While continuing to press the pedal, force the fluid in the system along with the air through the hose into the container. Once the pedal reaches its lowest position and the fluid stops flowing out through the hose, tighten the bleed screw all the way.
Repeat these steps until no more air comes out of the hose.
While holding the pedal down, tighten the bleed screw until it stops and remove the hose from the bleed screw.
Wipe the bleed nipple clean and install the protective cap.
