Caution! Be careful not to spill clutch fluid on painted surfaces. If this happens, wash off the fluid immediately with water.
Note: Do not mix different brands of clutch fluid.
Do not reuse drained clutch fluid.
Any hydraulic system will operate properly if the air is removed from it.
When bleeding, add only clean fluid recommended by the manufacturer. Never reuse fluid that has leaked from the hydraulic clutch release system.
If fluids of different grades are accidentally mixed in the hydraulic system, remove the fluid, flush with clean fluid of the required grade and install new O-rings.
If there are constant fluid leaks from the hydraulic drive or air gets into it, determine the cause and location of the leak and eliminate the damage.
Poorly performed bleeding of the hydraulic drive can cause incorrect diagnostic results and unjustified replacement of parts.
When performing any work on the clutch hydraulic drive, be sure to remove air from the following sections of the hydraulic circuit:
- between the tank and the air bleed nipple;
- between the air bleed nipple and the clutch slave cylinder;
- with increased free pedal travel.
Place the vehicle on a two-post lift.
Remove the engine oil pan guard.
Disconnect the brake fluid level sensor connector from the reservoir.
Remove the brake fluid reservoir cap.
Removal air from the circuit between the tank and the air bleed nipple
Install and lock the clutch pedal in the upper position.
Fill the hydraulic fluid reservoir with certified brake fluid.
Attach the installation (Ms. 554-07) to the hydraulic drive reservoir.
Remove the plug from the air bleed nipple.
Place a transparent tube on the bleed nipple of the clutch slave cylinder, lowering its end into an empty container installed below the bleed nipple.
Press the latch.
Attention! Do not pull the lock. Any erroneous action requires replacement of the pipeline.
Open the air bleed nipple by pulling the clutch hydraulic line out one click.
Turn on the pump of the installation (Ms. 554-07).
Wait until there are no air bubbles in the brake fluid flowing into the container.
Caution! Make sure that the fluid level is above the hydraulic line nipple when bleeding air.
The fixation of the clutch hydraulic drive pipeline should be accompanied by a characteristic click.
Shift the clutch in and out about ten times.
Bleeding the circuit between the bleed nipple and the clutch slave cylinder
Attach an empty syringe with a useful volume of 60 cm³ to the end of the transparent tube.
Press the latch.
Pull the clutch hydraulic line one click.
Turn on the pump of the installation (Ms. 554-07) and let the liquid fill the syringe
Slowly and completely force the fluid out of the syringe into the clutch hydraulic system (repeat the operation three times).

Close the bleed nipple by inserting the clutch hydraulic line as soon as the fluid starts to flow out without bubbles.
Remove the syringe and clear tube from the air bleed nipple.
Place the plug on the air bleed nipple.
Shift the clutch in and out about ten times.
Add fluid to tank 8 up to the maximum level mark.
Check the clutch for proper operation. Repeat the operation if necessary.
