MV6844 European Pressure Bleed System


Model MV6844 is a professional hydraulic brake and clutch bleeding system. Includes a fluid dispenser with manual pump (MV6400) and a single master cylinder adapter designed for use on most European cars (MVA804). It forces new brake fluid down through the master cylinder, while air and old fluid are expelled through the bleed screw(s). A pressure gauge on the Dispenser allows control of the system pressure, and the pressurized reservoir allows the operator hands-free movement to the bleed screws.
