You will need: key «at 11», brake fluid, transparent container, rubber hose.
Due to the fact that the clutch release hydraulic drive and the working brake system are combined in one reservoir, the replacement of the working fluid in the clutch release hydraulic drive occurs when the brake fluid in the brake hydraulic drive is changed. According to the manufacturer's recommendation, the fluid should be replaced after 30 thousand kilometers or 2 years of operation (whichever comes first).
To replace the working fluid, pump the hydraulic clutch release (see «Bleeding the hydraulic clutch release»). The criterion for the completion of the replacement is the termination of the output of the old (dirty) brake fluid from the bleed valve on the elbow of the hydraulic clutch release pipe.
