Pressure Bleeding (Non-Abs)

  1. Deplete vacuum reserve from power brake booster by depressing brake pedal several times with engine off. Clean master cylinder reservoir cap and surrounding area. Remove cap. Check and fill brake fluid reservoir.
  2. Ensure pressure bleeder tank is properly filled with clean uncontaminated DOT 3 brake fluid. Connect pressure bleeder, using proper adapter(s). Adjust pressure bleeder to 5-10 psi (.35-.70 kg/cm2 ). Ensure there is no leakage between pressure bleeder and master cylinder reservoir.
  3. Adjust pressure bleeder to 30-35 psi (2.11-2.46 kg/cm2 ). Raise and support vehicle. Attach bleeder hose to first bleeder valve to be serviced. See BRAKELINE BLEEDING SEQUENCE  table. Submerge other end of hose in clean transparent container, partially filled with clean brake fluid.
  4. Slowly open bleeder valve and allow fluid to flow. When fluid flowing into container is clear and free of bubbles, close bleeder valve and tighten to specification. See TORQUE SPECIFICATIONS  . Repeat for each remaining bleeder valve. See BRAKELINE BLEEDING SEQUENCE  table.
  5. Release pressure of bleeder. Disconnect pressure tank from master cylinder. Check brake fluid level. Fill as necessary. Ensure brake pedal feels firm and constant, and pedal travel is not excessive. Start engine and check brake pedal for firmness. If okay, road test vehicle, performing several stops from moderate speed. If spongy pedal, soft pedal or excessive pedal travel exists, repeat bleeding procedure.
