1. INSTALL BRAKE MASTER CYLINDER SUB-ASSEMBLY

NOTICE:
  1. The master cylinder and piston are designed so that the piston can easily fall out. Prevent this by making sure to tip of the master cylinder points downward when handling the master cylinder.
  2. Make sure foreign matter does not attach to the master cylinder's piston. If foreign matter attaches, clean it off with a cloth. Then apply lithium soap base glycol grease to the entire outer circumference contact surface area of the piston.
  1. Install a new O-ring to the master cylinder.

    14 N*m{ 144 kgf*cm , 10 ft.*lbf }

    HINT:
    1. Use a torque wrench with a fulcrum length of 300 mm (11.8 in.).
    2. This torque value is effective when the union nut wrench is parallel to the torque wrench.


4. BLEED AIR FROM BRAKE LINE



C126435E01

  1. Remove the bleeder plug cap.

  1. Connect the vinyl tube to the bleeder plugs.

  1. Depress the brake pedal several times, and then loosen the bleeder plug with the pedal depressed.

  1. When fluid stops coming out, immediately tighten the bleeder plug. Then release the pedal.

  1. Repeat the 2 previous steps until all the air in the brake fluid is gone.

  1. Tighten the bleeder plug.

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

  1. Bleed air from the brake line for each wheel by repeating the above procedures.



5. BLEED AIR FROM CLUTCH LINE (for Manual Transaxle)
  1. Fill the brake reservoir with brake fluid and bleed the clutch system.

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


6. BLEED AIR FROM ABS AND TRACTION ACTUATOR ASSEMBLY (w/ VSC)

NOTICE:
After bleeding the air from the brake system, if the height or feel of the brake pedal cannot be obtained, perform air bleeding of the brake actuator with an intelligent tester by following the procedure below.
  1. Depress the brake pedal more than 20 times with the engine off.

  1. Connect the intelligent tester to the DLC3, and turn the ignition switch on (IG).

    NOTICE:
    Do not start the engine.
  1. Select AIR BLEEDING on the intelligent tester.

    HINT:
    Refer to the intelligent tester operator's manual for further details.
  1. Bleed the air out of the suction line.

    NOTICE:
    1. Perform the bleeding at the right front wheel and right rear wheel.
    2. Bleed the air by following the steps displayed on the intelligent tester.

    1. Connect a vinyl tube to the bleeder plug at the right front wheel or the right rear wheel.

    2. Loosen the bleeder plug.

    3. Operate the brake actuator to bleed the air using the intelligent tester.

      NOTICE:
      Release the brake pedal at this time.

      HINT:
      This operation stops automatically after 4 seconds.
    4. Check if the operation has stopped by referring to the intelligent tester display.

    5. Temporarily tighten the bleeder plug.
