BRAKE MASTER CYLINDER (for LHD) REMOVAL

Note

While the battery is connected, even if the engine switch is off, the brake control system activates when the brake pedal is depressed or the door courtesy switch turns on. Therefore during servicing of the brake system components, do not operate the brake pedal and open/close the doors while the battery is connected.


  1. PRECAUTION

    CAUTION:

    Be sure to read Precaution thoroughly before servicing Click here.

    Note

    After turning the engine switch off, waiting time be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notice before proceeding with work Click here.

  5. DISCONNECT BRAKE ACCUMULATOR PUMP CONNECTORS


    1. A01GL4Y

      With the power switch off, disconnect the 2 brake accumulator pump connectors.

  6. PERFORM ACCUMULATOR ZERO DOWN


    1. Drain the brake fluid in the reservoir tank near the MIN line.

    2. Connect the intelligent tester to the DLC3 with the power switch off.

    3. Turn the power switch on (IG).

    4. Turn the intelligent tester on and enter the following menus: Chassis / ABS/VSC/TRC / Utility / ECB (Electronically Controlled Brake system) Utility / Zero Down.

      Tech Tips

      Using the intelligent tester to perform accumulator zero down causes the pressurized fluid in the accumulator to be returned to the brake fluid reservoir.

    5. When the buzzer sounds, turn the power switch off.

    6. Turn the intelligent tester off.

  7. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

    Note

    When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.
