Bleeding [12/2013 - ]: Procedure

  1. FILL RESERVOIR WITH BRAKE FLUID 

    See step  1

  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 brake master cylinder sub-assembly to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.

    HINT: 

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

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

      NOTE:
      • Do not kink or damage the brake lines.
      • Do not allow the brake lines to twist or interfere with other parts or the vehicle body during tightening.
      • Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.
      • Use the formula to calculate special torque values for situations where the union nut wrench is combined with a torque wrench.

        Refer to PRECAUTION [12/2013 - 11/2016] , or refer to PRECAUTION [11/2016 - ]

  3. BLEED BRAKE LINE

    • After bleeding the brake system, if the required height or feel of the brake pedal cannot be obtained, perform air bleeding of the brake actuator assembly with the Techstream by following the procedure below.
    • To prevent brake fluid from damaging painted surfaces, cover any surrounding parts with a piece of cloth.
    1. Depress the brake pedal more than 20 times with the ignition switch off.
    2. Connect the Techstream to the DLC3.
    3. Turn the ignition switch to ON and turn the Techstream on.
