LOAD SENSING PROPORTIONING VALVE INSTALLATION


  1. INSTALL LOAD SENSING W/SPRING VALVE ASSEMBLY


    1. A01BH3H

      Install the load sensing with spring valve assembly with the 2 bolts.

      Torque:
      32 N*m  { 326 kgf*cm, 24 ft.*lbf }

    2. Using a union nut wrench, install the 3 brake tubes to the load sensing with spring valve assembly.

      Torque:
      15 N*m  { 155 kgf*cm, 11 ft.*lbf }

      Note

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

    3. A01BHJS

      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

  3. BLEED BRAKE SYSTEM


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

      2. Rear bleeder plug:

        Torque:
        11.0 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

  5. CHECK BRAKE FLUID LEAKAGE

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


    • A01BF50

    • 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. A01BAFXE01

      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. A01BGHH

      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.
