BRAKE FLUID BLEEDING

CAUTION / NOTICE / HINT

Note


  • Move the shift lever to P and apply the parking brake before bleeding the brakes.

  • Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brakes.

  • If brake fluid leaks onto any painted surface, immediately wash it off.

  • Do not operate the brake actuator assembly while air is in the brake system or in the brake master cylinder sub-assembly. Doing so may cause air to enter the brake actuator assembly.

  • If bleeding the brake actuator assembly is difficult due to air in the brake actuator assembly, replace it with a new one.

Tech Tips

If any work is performed on the brake system or if air in the brake lines is suspected, bleed the air from the brake system.

PROCEDURE


  1. FILL RESERVOIR WITH BRAKE FLUID

  2. BLEED BRAKE MASTER CYLINDER

    Note


    • To prevent brake fluid from damaging painted surfaces, cover any surrounding parts with a piece of cloth.

    • Be sure to clean your hands before bleeding from 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 problem.

    Tech Tips

    If the brake master cylinder sub-assembly is reinstalled or runs out of brake fluid, bleed the brake master cylinder sub-assembly.


    1. A01W3UU

      Using a union nut wrench, disconnect the 2 brake lines from the brake master cylinder sub-assembly.

    2. A01W3SH

      Slowly depress the brake pedal and hold it.*1

    3. A01W04S

      Cover the 2 outer holes with fingers, and release the brake pedal.*2

    4. Repeat steps *1 and *2, 3 or 4 times.

      *a Torque Wrench Fulcrum Length

      Using a union nut wrench, connect the 2 brake lines to the brake master cylinder sub-assembly.

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

      Note


      • Do not kink or damage the brake lines.

      • Do not allow brake lines to twist and interfere with other parts or vehicle body during flexible hose tightening.

      • Do not allow any foreign matter such as dirt or dust to enter the brake lines.

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

      • When using a union nut wrench (fulcrum length of 20 mm (0.787 in.)) + torque wrench (fulcrum length of 250 mm (9.84 in.)):

        18 N*m (184 kgf*cm, 13 ft.*lbf)

  4. BLEED BRAKE ACTUATOR

    Note

    After bleeding the air from the brake system, if the correct height or feel of the brake pedal cannot be obtained, bleed the air from the brake actuator assembly using the GTS by following the procedure below.


    1. Depress the brake pedal more than 20 times with the engine switch off.

    2. Connect the GTS to the DLC3, then turn the engine switch on (IG).

      Note

      Do not start the engine.

    3. Turn the GTS on and enter the following menus: Chassis / ABS/VSC/TRC / Utility / Air Bleeding.

    4. Bleed brake actuator by following the instructions on the GTS.

    5. After air bleeding, tighten each bleeder plug.

      Torque:
      8.3 N*m  { 85 kgf*cm, 73 in.*lbf }

    6. Turn the GTS off and disconnect the GTS from the DLC3.

    7. Turn the engine switch off.
