Since the clutch hydraulic system works on brake fluid, it is necessary to follow the instructions given in Section Removal of air from the brake system.
Brake fluid is poisonous. Never suck it out by mouth through a hose. Store brake fluid only in containers that cannot be accessed by accident.
Caution: Do not allow brake fluid to get into the gearbox, if this happens, wipe off the fluid immediately. It is especially dangerous to get brake fluid on a magnesium alloy gearbox.
The operation of lifting and placing the vehicle on stands is dangerous! Therefore, before carrying out the operation, read Section Jacking and towing.
1. Raise and place the vehicle on stands and remove the bottom cover, if equipped.
Air removal with a special device
At service stations, air is removed from the hydraulic system, as a rule, using a device. This device generates pressure (Max. 2.5 atm.) in the liquid reservoir.
1. Turn away screws and remove a cover of the reservoir of a brake liquid. Fill the reservoir with liquid up to the MAX mark.
2. Connect the bleeder according to its manual, without turning it on yet.
3. Open the ventilation valve before switching on the instrument.
4. Pull out the clutch pedal before bleeding.
5. On the clutch slave cylinder, put on the hose (A) on the ventilation fitting (arrow on accompanying illustration), the fitting is open. Connect the breather hose to the brake fluid reservoir hose.
6. Switch on the device and release approximately 100 cm3 of brake fluid. This corresponds to the volume of a tea cup. At the end of the removal procedure, the air from should not contain bubbles. Torque the fitting 4.5Nm.
7. Press the clutch pedal several times.
8. Fill reservoir with fluid up to the MAX line. Screw the lid onto the tank.
9. If necessary, repeat the bleed process.
10. Reinstall the gearbox bottom cover if it was removed.
Air removal without the use of special devices
1. Check the level of brake fluid in the common tank, if necessary, add fluid to the MAX mark.
2. Remove anthers from the union of removal of air on the working cylinder and from a support of a forward left wheel.
3. Carefully open and close the air vents.
4. Put a transparent hose on the caliper fitting.
5. Fill the hose with brake fluid. To do this, open the fitting on the caliper. Ask an assistant to slowly press the brake pedal and hold it in this position. Close the choke and release the pedal. Then open the choke again and depress the pedal again. Repeat the process until the hose is filled with brake fluid. Close the hose with your finger to prevent fluid from escaping.
Caution: The liquid level in the tank must not fall too low, top up if necessary.
6. Put the free end of the hose on the clutch slave cylinder bleeder valve and open both connectors.
7. Press a brake pedal, close the union on a support and release a pedal. Repeat this process as many times as necessary to ensure no air bubbles enter the reservoir. At the same time, constantly add fluid.
8. Close the fittings on the caliper and clutch slave cylinder. Remove the hose and put on the anthers.
9. Lower the car onto its wheels.
10. Fill the reservoir with brake fluid up to the MAX mark.
11. Press the brake pedal several times. This ensures that any remaining air in the system is expelled into the brake fluid reservoir.
12. Check the operation of the brake system and clutch.
Caution: The above process may leave some air in the hydraulic system. A sign of this is a rattle when shifting into gear and fuzzy clutch disengagement. In this case, bleed the air immediately with a workshop tool.
