REMOVAL

Removal / installation

NOTICE:
If brake fluid spills on any painted surface, wash or otherwise remove it completely.


1. PERFORM ACCUMULATOR ZERO DOWN

CAUTION:
  1. Never bleed air from the brake hydraulic system without using the intelligent tester. Failure to use the intelligent tester could cause serious injury or an accident.
  2. Be sure to perform this procedure before replacement, removal, or installation of the actuator.

NOTICE:
Perform accumulator zero down by following the steps displayed on the intelligent tester.

  1. Connect the intelligent tester to the DLC3 with the ignition switch off

  1. Depressurize the accumulator.

    1. Check that the parking brake is applied and turn the ignition switch to the ON position.

    2. Turn on the intelligent tester and select "DIAGNOSTIC MENU" → "ABS/VSC" → "ECB UTILITY" → "ZERO DOWN" on the intelligent tester.

    3. When the buzzer sounds, turn the ignition switch off.

  1. Circulate the fluid in the accumulator.

    1. Depressurize the accumulator 5 times.

      HINT:
      1. Accumulator pressure is released and accumulated repeatedly, which circulates the fluid inside the accumulator, when repeating accumulator zero down.
      2. The pump motor rotates and the accumulator is pressurized every time the ignition switch is turned from off to on.


2. REMOVE ABS MOTOR RELAY

  1. C108426
    Remove the 2 ABS motor relays with the ignition switch off in order to prohibit brake control.

    NOTICE:
    1. If the pump motor operates while air remains inside the brake actuator hose, the air will enter the actuator, resulting in difficulty in bleeding the brakes.
    2. After the brake actuator assembly has been replaced, remove the ABS motor relay before bleeding the brakes.


3. DRAIN BRAKE FLUID

4. REMOVE FRONT FENDER TO COWL SIDE SEAL RH

5. REMOVE FRONT FENDER TO COWL SIDE SEAL LH
