Only with hydraulic clutch
The clutch actuator must be bled of air when the clutch pedal does not return or returns slowly, and also if the hydraulic system has been opened.
Since brake fluid is used in the hydraulic clutch, you must also read the relevant information in the section «Removal of air from the brake system».
Raise the car in front.
Check the level of brake fluid in the common compensation tank, if necessary top up the level to the mark «max».
Remove the dust caps from the bleed valve on the slave cylinder and on the front left brake caliper.
Carefully open the bleed valves.
Attach a transparent hose to the bleeder valve located on the disc brake caliper.
Fill the hose with brake fluid. To do this, open the air bleed valve located on the caliper. Slowly depress the brake pedal (performs assistant) and keep it in that position. Close the bleeder valve and release the brake pedal. Then open the valve again and depress the brake pedal again. Carry out the process until the hose is completely filled with brake fluid. Close the hose opening with your finger so that the brake fluid does not spill out.
Attention: The fluid level in the compensation tank must not fall too low, if necessary, top up the level with new brake fluid.
Put the hose closed with a finger on the bleed valve on the clutch slave cylinder and open both valves.
Depress the brake pedal, close the valve on the caliper, then release the brake pedal. Repeat this process until no more air bubbles enter the compensation tank. At the same time, constantly replenish the level in the reservoir with new brake fluid.
Close the bleed valves on the clutch slave cylinder and on the disc brake caliper. Remove the hose and put dust caps on the bleed valves.
Lower the car.
With the clutch pedal depressed, open the bleed valve on the master cylinder and close it again as soon as brake fluid comes out of it.
Top up the liquid level in the compensation tank to the mark «check».
Check the function of the brake system and clutch.
Caution: The venting process described here without a suitable device may leave some air in the system. This can be identified by scratching sounds when shifting into gear and improperly disengaging the clutch. In this case, it is urgent to remove air from the system in the workshop using an appropriate device. In the workshop, air is bled from the hydraulic clutch, usually using a bleeder. The device creates pressure in the brake fluid (maximum 2.5 bar). When using the device, air is removed first from the main and then from the working cylinder.
