Bleeding the Skoda Octavia clutch release drive system

If, when the pedal is pressed all the way down, the Skoda Octavia clutch does not completely disengage (“leads”), which is accompanied by a characteristic grinding of gears when reverse gear is engaged, air may have entered the clutch hydraulic actuator. Remove it by bleeding the hydraulic drive.
In addition, pumping is performed when the hydraulic drive is filled with liquid after its replacement or after repair of system components associated with system depressurization.
You will need: brake fluid, bleed hose, 10 wrench, container for drained fluid.

1. Check the level of the working fluid in the reservoir of the main brake cylinder of the Skoda Octavia (the reservoir is common for both systems) and, if necessary, bring it to normal.
2. Remove the protective cap from the air bleed valve on the clutch slave cylinder.

3. Put a hose on the valve and lower its end into a container with a small amount of brake fluid. Have an assistant depress the clutch pedal four to five times at 2-3 second intervals and then keep it depressed. Loosen the valve 3/4 turn. Liquid with air bubbles will flow from the hose into the container.
4. Wrap the valve and ask to release the clutch pedal.
5. Repeat steps 3 and 4 several times until fluid begins to exit the hose without air bubbles.
WARNING
While bleeding the hydraulic drive, periodically check the fluid level in the reservoir of hydraulic brake drives and clutch release. Do not allow the liquid level in the tank to fall below 25 mm from its bottom. Top up the fluid in a timely manner, otherwise, when the bottom of the tank is drained, air will enter the system and pumping will have to be repeated again.
6. Wrap the valve, put on a protective cap and, if necessary, add fluid to the reservoir of hydraulic brakes and clutch release.
