      Tech Tips


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

      • When using a union nut wrench (fulcrum length of 22 mm (0.8661 in.)) + torque wrench (fulcrum length of 162 mm (6.3779 in.)): 13 N*m (137 kgf*cm, 10 ft.*lbf)

    3. B007SOW

      Install the load sensing spring bracket with the 2 nuts.

      Torque:
      13 N*m  { 133 kgf*cm, 10 ft.*lbf }

  2. ADD BRAKE FLUID

    Fluid
    SAE J1703 or FMVSS No. 116 DOT3 or equivalent

    Note

    Do not remove the filter from the brake master cylinder reservoir and be sure to fill with new brake fluid to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.

  3. BLEED BRAKE LINE


    1. Connect the vinyl tube to the bleeder plug.

    2. Depress the brake pedal several times and loosen the bleeder plug with the pedal held down.

    3. At the point where the fluid stops coming out, tighten the bleeder plug and release the brake pedal.

    4. Repeat this procedure until the air in the brake fluid is completely bled out.

    5. Tighten the bleeder plug.


      1. Front bleeder plug:

        Torque:
        11 N*m  { 110 kgf*cm, 8 ft.*lbf }

      2. Rear bleeder plug:

        Torque:
        11 N*m  { 112 kgf*cm, 8 ft.*lbf }

    6. Repeat the above procedure to bleed the air out of the brake line for each wheel.

  4. INSPECT BRAKE FLUID LEVEL IN RESERVOIR


    1. Check the fluid level and add fluid if necessary.

      Fluid
      SAE J1703 or FMVSS No.116 DOT3 or equivalent

      Note

      Do not remove the filter from the brake master cylinder reservoir and be sure to fill with new brake fluid to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.

  5. CHECK BRAKE FLUID LEAKAGE

  6. RAISE FRONT BRAKE PRESSURE 9,807 kPa (100 kgf/cm2, 1,422 psi) AND CHECK REAR BRAKE PRESSURE


    • B007TX3

    • Tech Tips

      Gradually depress on the brake pedal until the pressure reaches the specified valve. Do not overshoot the specified pressure. Read the value of rear pressure 2 seconds after adjusting to the specified fluid pressure.

  7. IF NECESSARY, ADJUST FLUID PRESSURE


    1. B007R4WE01

      Adjust the length of the shackle.

      Lower pressure - Lengthen "A"

      High pressure - Shorten "A"

      Initial set
      120 mm (4.72 in.)
      Adjusting
      112 to 128 mm (4.40 to 5.04 in.)
    2. B007Q6G

      If the pressure cannot be adjusted by the shackle, raise or lower the valve body.

      Lower pressure - Lower

      High pressure - Raise

    3. Torque the nuts.

      Torque
      12.5 N*m (130 kgf*cm, 9 ft.*lbf)

    4. Adjust the length of the shackle again.

      If it cannot be adjusted, inspect the valve body.
