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 Multi-mode Manual Transaxle:

    Move the shift lever to N 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.

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 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. A01TDH6

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

    2. A01TAYA

      Slowly depress the brake pedal and hold it.*1

    3. A01TAJG

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

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

    5. A01TAY9C01
      *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 (w/o VSC)
      15.2 N*m  { 155 kgf*cm, 11 ft.*lbf }
      Specified tightening torque (w/ VSC)
      19.5 N*m  { 199 kgf*cm, 14 ft.*lbf }

      Note


      • Do not bend or damage the brake lines.

      • Do not allow the brake lines 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 lines.

      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 22 mm (0.866 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):

        w/o VSC: 13.38 N*m (136 kgf*cm, 10 ft.*lbf)

      • When using a union nut wrench (fulcrum length of 20 mm (0.787 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):

        w/ VSC: 17.36 N*m (177 kgf*cm, 13 ft.*lbf)
