Clean master cylinder cap and surrounding area, then remove cap. With pressure tank at least 1/3 full, connect to 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.

NOTE: Follow equipment manufacturers pressure specifications, except if noted below.

Unscrew bleeder valve 3/4 -1 turn noting fluid flow. When fluid flowing from cylinder to cup is free of bubbles, close bleeder valve securely. Bleed remaining cylinders in correct sequence and in the same manner. Remove tool from combination valve.
