  5. BLEED BRAKE LINE (for Hydraulic Brake Booster)


    1. Turn the ignition switch to ON.

    2. Remove the brake master cylinder reservoir filler cap assembly.

    3. Add brake fluid until the fluid level is between the MIN and MAX lines of the reservoir.

    4. Repeatedly depress the brake pedal and bleed air from the bleeder plug of the front disc brake cylinder RH.

    5. Repeat the step above until the air is completely bled, and then tighten the bleeder plug while depressing the brake pedal.

      Tech Tips


      • Air is bled as the pump motor operates while the brake pedal is being depressed.

      • Be sure to release the brake pedal to stop the motor after approximately 100 seconds of continuous operation.

      • As brake fluid is continuously drained while the pump operates, it is not necessary to repeatedly depress the brake pedal.

    8. When there is no more air in the brake fluid, tighten the bleeder plug, and then release the brake pedal.

      Torque:
      11 N*m  { 110 kgf*cm, 8 ft.*lbf }

    9. Bleed the air from the bleeder plug of the rear disc brake cylinder LH using the same procedure as for the RH side.

    10. Turn the ignition switch off.

    11. Inspect for brake fluid leaks.

    12. Check and adjust the brake fluid level Click here.

    13. Clear the DTCs Click here.

  6. BLEED BRAKE LINE (for Vacuum Brake Booster)

    CAUTION:

    If air is bled without using the intelligent tester, damage or accidents may result. Therefore, always use the intelligent tester when bleeding air.


    1. Remove the brake master cylinder reservoir filler cap assembly.

    2. Add brake fluid until the fluid level is between the MIN and MAX lines of the reservoir.

    3. Using a union nut wrench, disconnect the 2 brake tube from the master cylinder.

    4. Slowly depress and hold the brake pedal.

    5. Block the tube holes with your fingers, and then release the brake pedal.

    6. Remove your fingers, slowly depress and hold the brake pedal, block the tube holes with your fingers again, and then release the brake pedal. Repeat this step 3 or 4 times.

    7. Using a union nut wrench, connect the 2 brake tubes to the brake master cylinder assembly.

      Torque:
      20 N*m  { 199 kgf*cm, 14 ft.*lbf }

      Note

      Use the formula to calculate special torque values for situations where a union nut wrench is combined with a torque wrench Click here.

    8. Loosen the bleeder plug of the front brake cylinder RH.

    9. Repeatedly depress the brake pedal and bleed the air from the bleeder plug of the front brake cylinder RH.

      Note

      Add fluid as necessary so that the fluid in reservoir does not decrease below the MIN level.

    10. After air is completely bled out, tighten the bleeder plug while depressing the brake pedal.

      Torque:
      11 N*m  { 110 kgf*cm, 8 ft.*lbf }

      Note

      Add fluid as necessary so that the fluid in the reservoir does not decrease below the MIN level.

    14. After the air is completely bled out, tighten the bleeder plug while depressing the brake pedal.

      Torque:
      11 N*m  { 110 kgf*cm, 8 ft.*lbf }

    15. Bleed the air from the bleeder plug of the rear disc brake cylinder LH using the same procedure as for the RH side.

    16. Turn the ignition switch off and connect the intelligent tester to the DLC3.

    17. Turn the ignition switch to on and turn the tester on.

      Note

      Do not start the engine.

    18. Enter the following menus: Chassis / ABS/VSC/TRC / Utility / Air Bleeding.

    19. Select and run "Inhalation" from the Air Bleeding screen on the intelligent tester.

      Note

      Follow the prompts on the tester screen to bleed the air for both wheels (front and rear) on the right side.

    20. Loosen the bleeder plug of the right front wheel.*1

    21. Using the intelligent tester, operate the actuator.

      Tech Tips


      • To protect the actuator, the operation stops automatically.

      • Make sure the brake pedal is released.

    22. Check the intelligent tester screen to confirm that the operation stopped.

    23. Tighten the bleeder plug.*2

    24. Repeat the procedures above from *1 to *2 until the air is completely bled out.
