Pressure Bleeding

  1. Clean master cylinder cap and surrounding area. Remove cap. With pressure tank at least 1/2 full, connect to master cylinder with adapters. Attach bleeder hose to first bleeder valve to be serviced. See BLEEDING SEQUENCE  table.
  2. Place other end of hose in clean glass jar partially filled with clean brake fluid so end of hose is submerged in fluid. The hold off valve must be positioned properly before pressure bleeding (if equipped). See HYDRAULIC CONTROL VALVES  under BRAKE SYSTEM BLEEDING in this article.
  3. Open release valve on pressure bleeder. Follow equipment manufacturer's pressure instructions or see PRESSURE BLEEDER SETTINGS  table. Open bleeder screw 3/4-1 turn and note fluid flow.
  4. Close bleeder screw when fluid flowing is free of bubbles. Repeat procedure on remaining wheels in proper sequence. Check brake pedal operation after bleeding has been completed.
  5. Remove pressure bleeding equipment and valve retainer from hold off valve. Ensure that master cylinder is full of fluid.
