The Brake-Pro Electric Pressure Brake Bleeder features a user friendly fully digital LCD screen and touch panel with multi language display. Designed with a top-tier digitally controlled seal-less gear pump and robust hydraulic system. Auto leveling of the brake fluid reservoir within the same circuit allows for the hydralic system to work both ways with an internal flushing mode that can be used to exchange fluid. Operates within a pressure range of 0.5 to 4.5 bar (7.2-65.2 psi).
