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.

  • for 1AD-FTV:

    If bleeding is performed with the engine running or the ignition switch ON, DTC C1441 will be stored. Make sure to clear the DTCs when work is complete.

Tip:

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.

    Tip:

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

    1. C273646

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

    2. C164389

      Slowly depress the brake pedal and hold it.*1

    3. C164390

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

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

    5. C273646

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

      w/o VSC

      15.2 N*m

      155 kgf*cm

      11 ft.*lbf

      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.

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