Warning: The brake fluid used in the hydraulic clutch system is poisonous, so if it comes into contact with the skin, immediately wash the area with plenty of water. If the liquid gets into the eyes or inside the body, you should immediately consult a doctor. Some fluids tend to be highly flammable and can ignite even from contact with hot vehicle components. In addition, the fluid used in the hydraulic clutch system dissolves paint and plastic, so if fluid comes into contact with the car's paintwork, wash it with plenty of water. Also, this liquid is hygroscopic, that is, it absorbs moisture from the air, and therefore it is not recommended to use liquid stored for a long time in an open container.
Any hydraulic system operates normally and reliably when air is removed from the hydraulic fluid in the system.
Warning: When bleeding, add only clean fluid of the correct type. Never reuse fluid that has leaked from the hydraulic clutch system.
Warning: If fluids of different types are accidentally mixed in the hydraulic system, remove the fluid from the hydraulic system, flush the system with clean fluid of the correct type, and install new O-rings.
If hydraulic fluid leaks continuously or air enters the hydraulic system, determine the cause and location of the leak and repair the damage.
Order of execution
1. Raise the front of the car and secure it on stands.
2. Remove the lower engine mudguard.
3. Check that the hydraulic tube and clutch hose connections are tight and that the bleed screw on the back of the clutch slave cylinder is screwed on. Remove the dust caps from the clutch slave cylinder bleeder and front brake caliper bleeders and clean any traces of dirt around the bleeders.
4. Put a transparent hose on the front brake caliper bleeder.
5. Fill the hose with brake fluid. To do this, press the brake pedal and unscrew the bleed valve half a turn while pressing the pedal. Continuing to press the pedal, force the liquid in the system into a transparent hose. After the pedal has reached its full forward position and fluid has stopped flowing into the hose, screw the bleeder in until it stops. Repeat these operations until the hose is filled with brake fluid. Maintain a transparent hose so that brake fluid does not spill out of it.
6. When performing this operation, do not let the brake fluid level fall below the middle of the reservoir.
7. Put the free second end of the transparent hose on the bleeder valve of the clutch slave cylinder and open both bleeder valves.
8. Depress the brake pedal and, while holding the pedal down, screw in the bleed screw on the brake caliper as far as it will go. Repeat this operation until air bubbles no longer appear in the reservoir of the brake system. When performing this operation, constantly add fresh brake fluid.
9. Screw in the bleeder fittings until they stop and remove the transparent hose from them.
10. Wipe the bleeder fittings and install protective caps on them.
11. Check the clutch pedal for smooth travel. If the clutch pedal jerks when pressed, there is air in the clutch hydraulic system. If, after re-bleeding the clutch pedal again, it moves unevenly, then the sealing rings of the clutch master or slave cylinder are worn out.
12. Install the lower engine mudguard and lower the vehicle.
