Attention: The brake fluid used as a working fluid in the clutch drive path is one of the toxic and chemically aggressive compounds and, in contact with body panels, destroys the paintwork. Before proceeding with the procedure, cover the wings and front panel of the car with special covers, or just old blankets. Bleed the brake system while wearing goggles. If brake fluid accidentally gets into your eyes, rinse immediately with plenty of water and seek medical attention!
1. The hydraulic clutch release must be bled each time the components are removed or when the fluid level in the reservoir drops enough to allow air into the master cylinder. When bleeding, use only fresh brake fluid of the required grade (D0T-4). Make sure that the union connections of the hydraulic clutch path are tight.
Attention: Do not reuse liquid pumped out of the system, as well as liquid stored for a long time in a loosely closed container!
2. The hydraulic path is bled through a special connection using a set of special equipment that is used to bleed the service brake system.
Attention: Manual bleeding of the actuator is no longer permitted!
The general connection diagram of the kit is shown on Ref. illustrations - before using the kit, carefully read the instruction manual for its operation.
3. Remove the master cylinder reservoir cap and fill the reservoir with fresh hydraulic fluid, bringing the level to the MAX mark. Connect a special adapter to the tank (see illustration 4.2) and attach the MKM-6174-2 device to it - lower the free end of the hose into a suitable drain container. Remove the protective cap of the bleed connection and connect the MKM-6174-2 tool to it. Connect the other end of the device to the pumping device.
4. Turn on the pumping device, turn the clutch (see illustration 4.2) 2-3 turns, this will open the valve for pumping. Bleeding should be continued until no more air bubbles come out of the drain hose. At the end of the procedure, manually tighten the coupling, turn off the device and remove all installed components. Remove traces of brake fluid leaks.
5. On models equipped with an Easytronic robotic gearbox, before connecting the bleeder, you must first remove the battery from the pallet. The device should only be used in conjunction with the TESN-2 diagnostic device - carefully read the instructions for the device. The location of the bleed connection is shown on Ref. illustrations.
Note: On these models, the adapter is mounted on the clutch fluid reservoir.
Attention: If the slightest amount of mineral oil gets into the brake fluid of the Easytronic system, the clutch will fail!
6. Checking the level of brake fluid in the reservoir of the Easytronic system is also carried out with the battery support tray removed - the level should be between the marks «MIN» And «MAX» (see resist. illustration).
7. Check the clutch drive for proper operation and all drive components for leaks.
