We pump the clutch hydraulic drive to remove air from it after depressurization when replacing the main or working clutch cylinders, tubes and hoses, as well as when removing the main brake cylinder or reservoir of the brake and clutch hydraulic drives.
Before pumping, check the fluid level in the tank. Add liquid if necessary.
Remove the protective cap from the clutch bleed valve.
With a "10" spanner wrench, we loosen the tightening of the bleeder fitting, holding the hose adapter by the flats with a "19" wrench.
We put a hose on the tip of the fitting, the end of which we lower into a container partially filled with brake fluid.
Slowly press the clutch pedal several times. With the clutch pedal depressed, unscrew the bleeder screw by 1/2–3/4 turn.
In this case, part of the brake fluid and air are forced out into the container.
Air bubbles are clearly visible in the liquid container. Keeping the pedal depressed, we wrap the fitting and repeat this operation until the exit of air bubbles from the hose stops.
Remove the hose and put a protective cap on the fitting.
When removing air from the system, we control the level of liquid in the tank and, if necessary, add liquid.
