Normal Brake System Air Bleeding

If the brake fluid level in the HBB reservoir is between the "MIN" and "MAX" lines after any brake servicing at the wheels (such as calipers, rotors, etc.), perform the following steps:

1. Bleed rear brake system as follows (right rear first, then left rear):
   CAUTION:

   • Keep the brake fluid reservoir level just above the "MIN" line at this time. Monitor the fluid level during this procedure to ensure it does not reach below the "MIN" line.
   • If a large quantity of brake fluid is drained during the bleeding procedure, the accumulator pressure will decrease abnormally. Do not bleed more than .11 Qt. (.1 L) from each wheel at a time.
   • Confirm that the pump motor stops after each air bleeding step.
   1. Attach the clear hose to the right rear caliper to monitor air/fluid flow.
   2. Turn the ignition switch to the "ON" position.
   3. Open bleeder valve 1/4 turn.
   4. With the bleeder valve open, pump the brake pedal 3 times and hold.
   5. Close the bleeder valve.
   6. Pump the brake pedal 3 times and hold.
   7. Open the bleeder valve 1/8 turn briefly to allow any remaining air to escape, then close the bleeder valve.
   8. Repeat steps f  and g  as many times as necessary to eliminate all air in the line.
   9. Repeat steps a  -h  at the left rear caliper.
2. Bleed front brake system as follows (right front first, then left front):
   CAUTION:

   • Keep the brake fluid reservoir level just above the "MIN" line at this time. Monitor the fluid level during this procedure to ensure it does not reach below the "MIN" line.
   • If a large quantity of brake fluid is drained during the bleeding procedure, the accumulator pressure will decrease abnormally. Do not bleed more than .11 Qt. (.1 L) from each wheel at a time.
   • Confirm that the pump motor stops after each air bleeding step.
   1. Attach the clear hose to the right front caliper to monitor air/fluid flow.
   2. Turn the ignition switch to the "ON" position.
   3. Open bleeder valve 1/4 turn.
   4. With the bleeder valve open, pump the brake pedal 3 times and hold.
   5. Close the bleeder valve.
   6. Pump the brake pedal 3 times and hold.
   7. Open the bleeder valve 1/8 turn briefly to allow any remaining air to escape, then close the bleeder valve.
   8. Repeat steps f  and g  as many times as necessary to eliminate all air in the line.
   9. Repeat steps a  -h  at the left front caliper.
3. Adjust the brake fluid level as follows:
   1. Turn the ignition switch to the "LOCK" (OFF) position.
   2. Depress the brake pedal repeatedly (up to 40 times or more) until its depressing force suddenly feels very heavy (no pedal travel).
   3. Release the brake pedal.
   4. Adjust the brake fluid level between the "MIN" and "MAX" lines on the reservoir.
