  2. Attach a clear plastic hose (1) to the bleeder screw and feed the hose into a clear jar (2) containing enough fresh brake fluid to submerge the end of the hose.
  3. Open the bleeder screw at least one full turn or more to obtain a steady stream of brake fluid.
  4. After approximately 120-240 ml (4-8 ounces) of fluid have been bled through the brake circuit and an air-free flow is maintained in the clear plastic hose and jar, close the bleeder screw.
  5. Repeat this procedure at all the remaining bleeder screws.
  6. Check and adjust brake fluid level to the FULL mark on the reservoir.
  7. Check brake pedal travel and feel. If pedal travel is excessive or if the pedal feels excessively spongy, some air may still be trapped in the system. Re-bleed the brakes as necessary including the IPB Caliper Brake Bleeding Procedure on the rear calipers as listed below.
    NOTE:

    If the system is not fully operational after performing the bleed procedure, repeat the entire procedure after waiting a few hours for the brake fluid to settle in the system.

  8. Test drive the vehicle to verify the brakes are operating properly and pedal feel is correct.
