Pressure Tank Bleeding
Clean master cylinder cap and surrounding area, then remove cap. With pressure tank at least 1/3 full, connect master cylinder using suitable adapters. Attach bleeder hose to first bleeder valve to be serviced. See BLEEDING SEQUENCE . Place other end of hose in clean glass jar, partially filled with clean brake fluid, so end of hose is submerged in fluid. Open release valve on pressure bleeder. Unscrew valve 3/4-1 turn, noting fluid flow. When fluid flow from bleeder valve into container is free of bubbles, close bleeder valve securely. Bleed remaining cylinders in correct sequence and in same manner. Remove pressure tank from master cylinder and check fluid level of master cylinder reservoir.
