  6. BLEED BRAKE LINE

    Note


    • Bleed the brake line of the wheel farthest from the master cylinder first.

    • Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brakes.

    2. Depress the brake pedal several times, and then loosen the bleeder plug with the pedal depressed (Step C).

    3. At the point where the fluid stops coming out, tighten the bleeder plug, and then release the brake pedal (Step D).

    4. Repeat Steps C and D until all the air in the fluid is completely bled out.

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

  7. BLEED BRAKE ACTUATOR ASSEMBLY (w/ VSC)

    Note

    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 the GTS by following the procedure below.


    1. Depress the brake pedal more than 20 times with the engine off.

    2. Connect the GTS to the DLC3, and turn the ignition switch to ON.

      Note

      Do not start the engine.

    3. Select "Air Bleeding" on the GTS.

      Tech Tips

      Refer to the tester operator's manual for further details.

    4. Bleed the air out of the brake line when Step 1: Increase appears on the GTS display.

      Note


      • Bleed the air by following the steps displayed on the GTS.

      • Make sure that the master cylinder reservoir tank does not become empty.


      1. B00458X

        Connect the vinyl tube to either one of the bleeder plugs.

      2. Depress the brake pedal several times, and then loosen the bleeder plug connected to the vinyl tube with the pedal depressed (Step E).

      3. When fluid stops coming out, tighten the bleeder plug and release the brake pedal (Step F).

      4. Repeat Steps E and F until all the air in the fluid is completely bled out.

      5. Tighten the bleeder plug completely.

        Torque:

        17 N*m  { 173 kgf*cm, 13 ft.*lbf }
        Front Brake for 2ZR-FE
        7.9 N*m  { 81 kgf*cm, 70 in.*lbf }
        Rear Brake (for Rear Disc Brake)
        14 N*m  { 143 kgf*cm, 10 ft.*lbf }
        Rear Brake (for Rear Drum Brake)
        9.5 N*m  { 97 kgf*cm, 84 in.*lbf }

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

    5. Bleed the air out of the suction line when Step 2: Inhalation appears on the GTS display.

      Note


      • Bleed the air by following the steps displayed on the GTS.

      • Make sure that the master cylinder reservoir tank does not become empty.


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

      2. Operate the brake actuator to bleed the air using the GTS (Step G).

        Note

        Release the brake pedal at this time.

        Tech Tips

        This operation stops automatically after 4 seconds.

      3. Check if the operation has stopped by referring to the GTS display and tighten the bleeder plug (Step H).

      4. Repeat Steps G and H until all the air in the fluid is completely bled out.

      5. Tighten the bleeder plug.

        Torque:
        Front Brake except 2ZR-FE
        17 N*m  { 173 kgf*cm, 13 ft.*lbf }

        9.5 N*m  { 97 kgf*cm, 84 in.*lbf }

      6. Repeat the above procedure for the other wheels to bleed the air out of the brake line.

    6. Bleed the air out of the pressure reduction line when Step 3: Decrease appears on the GTS display.

      Note


      • Bleed the air by following the steps displayed on the GTS.

      • Make sure that the master cylinder reservoir tank does not become empty.


      1. Connect a vinyl tube to either one of the bleeder plugs.

      2. Loosen the bleeder plug (Step I).

      3. Using the GTS, operate the brake actuator assembly, completely depress the brake pedal and hold it there (Step J).

        Note


        • During this procedure, the pedal will feel heavy, but completely depress it so that the brake fluid comes out of the bleeder plug.

        • Hold the brake pedal depressed. Do not depress and release the pedal repeatedly.

        Tech Tips


        • The operation stops automatically after 4 seconds. When performing this procedure continuously, set an interval of at least 20 seconds.

        • When the operation is complete, the brake pedal goes down slightly. This is a normal phenomenon caused when the solenoid opens.

      4. Tighten the bleeder plug, and then release the brake pedal (Step K).

      5. Repeat Steps I to K until all the air in the fluid is completely bled out.

      6. Tighten the bleeder plug.

      Note


      • Bleed the air by following the steps displayed on the GTS.

      • Make sure that the master cylinder reservoir tank does not become empty.


      1. B00458X
