BRAKE ACTUATOR REMOVAL

Tech Tips


  • Use the same procedure for the RHD and LHD vehicles.

  • The procedure listed below is for the LHD vehicles.

Note

While the battery is connected, even if the power 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 or open/close the doors while the battery is connected.


  1. REMOVE FRONT WHEEL LH

  2. REMOVE ENGINE ROOM SIDE COVER LH


    1. A01FV55

      Detach the 2 clips and remove the engine room side cover LH.

  3. REMOVE ABS MOTOR RELAY


    1. A01FSJ7

      Remove the 2 ABS motor relays with the power switch off in order to disable brake control.

      Tech Tips

      This procedure is not required if the 2 ABS motor relays have been removed.

  4. PERFORM ACCUMULATOR ZERO DOWN


    1. A01FU7GE01

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

    2. Connect the GTS to the DLC3 with the power switch off.

    3. Turn the power switch on (IG).

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

      Tech Tips

      Using the GTS 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 GTS off.

  5. DRAIN BRAKE FLUID


    1. Drain the brake fluid until it reaches the MIN level.

      Note

      Wash off brake fluid immediately if it comes in contact with any painted surface.

  6. PRECAUTION

    Note

    After turning the power switch off, waiting time may be required before disconnecting the cable from the auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the auxiliary battery terminal notice before proceeding with work Click here.
