BRAKE FLUID BLEEDING

CAUTION / NOTICE / HINT

Note


  • for Manual Transaxle:

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

  • for CVT:

    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.

  • When bleeding air, select the suitable procedure listed below.

    Replaced/Installed Item Work Procedure
    Flexible hose (front/rear) Bleed brake line
    Disc brake cylinder assembly (front)
    Brake actuator assembly
    Brake master cylinder sub-assembly
    Brake master cylinder reservoir sub-assembly
    Brake booster assembly

Tech Tips

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

PROCEDURE


  1. FILL RESERVOIR WITH BRAKE FLUID

  2. BLEED BRAKE MASTER CYLINDER SUB-ASSEMBLY

    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 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.

    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. B008KCQ

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

      Note


      • Do not damage or deform the brake lines during the removal procedure.

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

    2. B008KUX

      Slowly depress the brake pedal and hold it.*1

    3. B008KJY

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

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

    5. B008K54C01
      *a Torque Wrench Fulcrum Length

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

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

      Note


      • Do not kink or damage the brake tubes.

      • Do not allow the brake tubes to twist and interfere with other parts or vehicle body during tightening.

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

      Tech Tips


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

      • When using a union nut wrench (fulcrum length of 20 mm (0.787 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)): 17.4 N*m (177 kgf*cm, 13 ft.*lbf)
