Warning: The brake fluid used in the hydraulic clutch system is poisonous, so if it gets on your skin, immediately rinse the area with plenty of water. If the fluid gets into your eyes or inside your body, you should immediately consult a doctor. Some fluids are highly flammable and can catch fire even from contact with hot vehicle components. In addition, the fluid used in the hydraulic clutch system dissolves paint and plastic, so if the fluid gets on your vehicle's paintwork, rinse it with plenty of water. This fluid is also hygroscopic, meaning it absorbs moisture from the air, and therefore it is not recommended to use the fluid if it has been stored in an open container for a long time.
Any hydraulic system will operate properly and reliably if air is removed from the hydraulic fluid in the system.
When bleeding air, add only clean fluid of the correct type. Never reuse fluid that has leaked from the hydraulic clutch system.
If different types of fluids 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.
Execution order
1. Raise the front of the vehicle and support it on stands.
2. Remove the lower engine splash shield.
3. Check that the hydraulic tube and clutch hose connections are securely tightened and that the bleeder screw on the rear of the clutch slave cylinder is screwed in. Remove the dust caps from the bleeder screws on the clutch slave cylinder and front brake caliper and clean any traces of dirt from around the screws.
4. Attach the clear hose to the front brake caliper bleeder nipple.
5. Fill the hose with brake fluid. To do this, press the brake pedal and unscrew the bleeder screw half a turn while pressing the pedal.
6. While continuing to press the pedal, force the fluid in the system into the transparent hose. After the pedal reaches the extreme forward position and the fluid stops flowing into the hose, screw the bleeder nipple all the way in. Repeat these operations until the hose is filled with brake fluid. Support the transparent hose to prevent brake fluid from leaking out.
7. When performing this operation, do not allow the brake fluid level to fall below the middle of the reservoir.
8. Place the free second end of the transparent hose onto the clutch slave cylinder bleed nipple and open both bleed nipples.
9. Press the brake pedal and, while holding the pedal down, screw the bleeder screw on the brake caliper all the way in. Repeat this operation until no more air bubbles appear in the brake system reservoir. When performing this operation, constantly add fresh brake fluid.

10. Screw the bleed nipples all the way in and remove the transparent hose from them.
11. Wipe the bleed nipples and install protective caps on them.
12. Check the smoothness of the clutch pedal. If the clutch pedal moves jerkily when pressed, there is air in the clutch hydraulic system. If, after re-bleeding the air, the clutch pedal moves unevenly again, the sealing rings of the clutch master or slave cylinder are worn.
13. Install the lower engine splash shield and lower the vehicle.
