BRAKE MASTER CYLINDER (for TMT Made) INSTALLATION


  1. CHECK AND ADJUST BRAKE BOOSTER PUSH ROD

    Tech Tips

    Adjust the booster push rod when the master cylinder is replaced with a new one. Adjustment is not necessary when the master cylinder is reinstalled and the booster is replaced with a new one.


    1. A01DUXNE05

      Set SST on the master cylinder and lower the rod of SST until it just touches the piston.

      SST
      09737-00013

      Tech Tips

      SST 09737-00012 can also be used.

    2. Apply chalk to the flat tip of the rod of SST. Turn SST upside down and measure the clearance between the brake booster push rod and SST.

      Standard clearance
      0 mm (0 in.)

      If there is clearance between the main body of SST and the shell of the brake booster, the push rod is protrusion too far. If the chalk does not stick to the tip of the tip of the brake booster push rod, the push rod protrusion is insufficient.

    3. A01DVX6E01

      If the clearance is not as specified, adjust the length by holding the rod using SST and turning the tip of the rod using a 7 mm socket driver.

      SST
      09737-00020

      Note

      Check the push rod clearance again after adjusting.

  2. INSTALL BRAKE MASTER CYLINDER SUB-ASSEMBLY (w/ ABS)


    1. Install a new O-ring to the master cylinder.

    2. Install the master cylinder and bracket (with 3-way) to the booster with the 2 nuts.

    4. Connect the brake fluid level warning switch connector labeled B to the master cylinder.

    5. for Manual Transmission:

      Connect the clutch reservoir tube labeled A to the master cylinder.

  3. INSTALL BRAKE MASTER CYLINDER SUB-ASSEMBLY (w/o ABS)


    1. Install a new O-ring to the master cylinder.

    2. Install the master cylinder and bracket (with 4-way) to the booster with the 2 nuts.

      A01DVPXE02
      Torque:
      13 N*m  { 127 kgf*cm, 9 ft.*lbf }

    3. Using a union nut wrench, connect the 6 brake lines to the brake master cylinder and 4-way.

      A01DYV8E02
      Torque:
      15 N*m  { 155 kgf*cm, 11 ft.*lbf }

      Note

    4. Connect the brake fluid level warning switch connector to the master cylinder.

    5. Connect the clutch reservoir tube to the master cylinder.

  4. FILL RESERVOIR WITH BRAKE FLUID

    Fluid
    SAE J1703 or FMVSS No. 116 DOT 3

  5. BLEED AIR FROM BRAKE MASTER CYLINDER

    Tech Tips

    If the master cylinder has been disassembled or if the reservoir becomes empty, bleed air from the master cylinder.


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

    2. Slowly depress and hold the brake pedal.

    4. Repeat the 2 previous steps 3 or 4 times.

    5. Using a union nut wrench, connect the 2 brake lines to the master cylinder.

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

  6. BLEED AIR FROM BRAKE LINE


    1. Remove the bleeder plug cap.

    2. Connect the vinyl tube to the bleeder plugs.

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

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

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

    6. Tighten the bleeder plug.

      Torque:
      for front brake
      11 N*m  { 110 kgf*cm, 8 ft.*lbf }
      for rear brake (2WD)
      11 N*m  { 112 kgf*cm, 8 ft.*lbf }
      for rear brake (4WD and Pre-Runner)
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

    7. Install the cap.

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

    2. Connect the vinyl tube to the bleeder plug.

    3. Depress the clutch pedal several times, and then loosen the bleeder plug with the pedal depressed.

    4. At the point when fluid stops coming out, tighten the bleeder plug, and then release the clutch pedal.

  8. CHECK BRAKE FLUID LEVEL IN RESERVOIR


    1. A01DVQK

      Check the fluid level.

      If the brake fluid level is lower that the MIN line, check for leaks and inspect the disc brake pads. If necessary, refill the reservoir with brake fluid to the MAX line after repair or replacement.

      Fluid
      SAE J1703 or FMVSS No. 116 DOT 3

  9. CHECK FOR BRAKE FLUID LEAKAGE
