Bleeding [05/2019 - ]: Procedure

  1. BLEED BRAKE LINE 
    1. Remove the center No. 1 cowl top ventilator louver.

      See step  1

    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.

      Brake fluid

      SAE J1703 or FMVSS No. 116 DOT 3

      NOTE:

      Do not remove the filter from the brake master cylinder reservoir and be sure to fill with new brake fluid to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.

    4. Remove the bleeder plug cap.
    5. Connect the vinyl tube to the bleeder plugs.
    6. Depress the brake pedal several times, and then loosen the bleeder plug with the pedal depressed.*1
      NOTE:

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

    7. When fluid stops coming out, tighten the bleeder plug, and then release the brake pedal.*2
    8. Repeat *1 and *2 until all the air in the brake fluid is completely bled out.
    9. Tighten the bleeder plug completely.

      Torque: 8.3 N*m (85 kgf*cm, 73 in.*lbf) 

    10. Install the bleeder plug cap.
    11. Repeat the above procedure for each wheel to bleed the brake line.
    12. Check for brake fluid leaks.
    13. Check the brake fluid level in the reservoir.

      Refer to ON-VEHICLE INSPECTION [10/2014 - ] 

    14. Install the center No. 1 cowl top ventilator louver.

      See step  5

  2. BLEED BRAKE SYSTEM 
    WARNING:

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

    NOTE:

    Be sure to clean your hands before bleeding from the master cylinder to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.

    1. Remove the center No. 1 cowl top ventilator louver.

      See step  1

    2. Remove the brake master cylinder reservoir filler cap assembly.
    3. Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brakes.

      Brake Fluid

      SAE J1703 or FMVSS No. 116 DOT3

      NOTE:

      Do not remove the filter from the brake master cylinder reservoir and be sure to fill with new brake fluid to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.

    4. Using a union nut wrench, disconnect the 2 brake lines from the brake master cylinder.

      NOTE:
      • Do not kink or damage the brake lines.
      • Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.
    5. Slowly depress and hold the brake pedal.*1
    6. Block the puter holes with your fingers, and release the pedal.*2

    7. Repeat steps *1 and *2, 3 or 4 times.
    8. Using a union nut wrench, connect the 2 brake lines to the brake master cylinder.

      Specified tightening torque 

      Torque: 15.2 N*m (155 kgf*cm, 11 ft.*lbf) 

      HINT: 

      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

        Refer to PRECAUTION [05/2019 - ]

      • When using a union nut wrench (fulcrum length of 22 mm (0.8661 in.)) + torque wrench (fulcrum length of 162 mm (6.3779 in.)): 13.4 N*m (137 kgf*cm, 10 ft.*lbf)

    9. Remove the bleeder plug cap.
    10. Connect the vinyl tube to the bleeder plugs.
    11. Depress the brake pedal several times, and then loosen the bleeder plug with the pedal depressed.*1
      NOTE:

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

    12. When fluid stops coming out, tighten the bleeder plug, and then release the brake pedal.*2
    13. Repeat *1 and *2 until all the air in the brake fluid is completely bled out.
    14. Tighten the bleeder plug completely.

      Torque: 8.3 N*m (85 kgf*cm, 73 in.*lbf) 

    15. Install the bleeder plug cap.
    16. Repeat the above procedure for each wheel to bleed the brake line.
    17. Depress the brake pedal more than 20 times with the engine off.
    18. Connect the Techstream to the DLC3, and turn the engine switch on (IG).
      NOTE:

      Do not start the engine.

    19. Enter the following menus: Chassis / Brake / Utility / Air Bleeding.

      Chassis > Brake > Utility
