HYDRAULIC BRAKE BOOSTER (for LHD) REMOVAL

Note


  • When installing, coat the parts indicated by arrows with lithium soap base glycol grease Click here.

  • Be sure not to allow the pump to contact the floor; support it with the booster body. If the pump contacts the floor, the red brake tube between the pump and booster body may be deformed, the operating sound of the pump may become loud enough to hear within the cabin, and fluid may leak.

  • As high pressure is applied to the brake actuator tube No. 1, never deform it.

  • Do not turn the ignition switch to ON until the procedures are completed.

  • Before starting the work, make sure that the ignition switch is off and depress the brake pedal more than 20 times.

Tech Tips

When pressure in the power supply system is released, the reaction force decreases and the stroke becomes longer.


  1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

    CAUTION:

    Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.

    Note


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