6-speed manual transmission
Air must be removed from the clutch hydraulic system if the clutch pedal does not return or returns slowly, the clutch disengages poorly, or if the hydraulic system has been opened.
Security measures
Since the hydraulic clutch system works with brake fluid, it is necessary to familiarize yourself with the materials of Chapter Brake system.
Brake fluid is poisonous and damages the paintwork of your car.
Attention! During the process of air removal described here, some volume of air may remain in the system. A sign of this is scratching and incomplete disengagement of the clutch. In this case, air from the clutch hydraulic system must be immediately removed at a service station using a special device.
Removal air without using a special device
1. Check the level in the brake fluid reservoir, if necessary, add fluid to the system, refer to Chapter Routine maintenance.
Attention! Do not allow the liquid level in the tank to drop, constantly add liquid.
Note: The operation of lifting and installing the vehicle on stands is associated with danger! Therefore, before carrying out the operation, read Section Jacking and towing Introduction to the manual.
2. Raise and place the vehicle on stands.
3. Remove the bottom cover.
4. Remove the dust cap from the air bleed nipple (arrow on the working cylinder). Place a transparent hose on the fitting.
Note: The accompanying illustration is for informational purposes only and does not fully correspond to the model described.
5. Carefully rotate the nipple. Use a spanner to open it so as not to damage the hexagon of the nipple.
6. Place the free end of the hose in a container with brake fluid so that air does not enter the system during the bleeding process.
7. Ask an assistant to press the clutch pedal all the way down about 10 times and then leave the pedal depressed.
8. In this position, open the bleed screw, and the brake fluid will start to flow out. When there is no more air in the flowing fluid or if the fluid pressure drops, close the bleed screw.
Attention! Do not allow the fluid level in the tank to drop significantly, add new fluid all the time.
9. Release the clutch pedal and press it again 10 times. Keeping the pedal in this position, open the nipple. Repeat this procedure as many times as necessary until no air bubbles are visible in the hose. At the same time, constantly add new fluid to the reservoir.
Caution! If the brake fluid needs to be completely replaced, bleed the air until new fluid appears in the hose. This is indicated by a lighter color.
10. Close the nipple on the slave cylinder. Remove the hose and put on the dust cap.
11. Replace the bottom cover.
12. Fill the tank with liquid up to the MAX mark.
13. Check the operation of the brake system and clutch.
Removal air using a device
At the service station, air is removed from the clutch system, as a rule, using a special device. This device creates fluid pressure in the system. Below is a description of only the differences from the above-described method of removing air without using a device.
1. Connect the device to the brake fluid reservoir as described by the manufacturer.
2. Remove the dust cap from the air bleed nipple on the clutch slave cylinder. Attach a hose to the nipple. Place the end of the hose in a bottle of brake fluid.
3. Open the nipple and keep it open until air stops escaping, then close the nipple.
Caution! If the brake fluid needs to be completely replaced, bleed the air until new fluid appears in the hose. This is indicated by a lighter color.
4. Place the dust cap on the nipple.
5. Remove the air bleeder.
6. Fill the reservoir with brake fluid to the MAX mark and close the reservoir.
