Removal & Installation

REMOVAL

CAUTION:

• While electrically-driven intelligent brake unit is removed, hold part with hand.

  

• Never disassemble electrically-driven intelligent brake unit.

• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off immediately and wash with water if it gets on a painted surface. For brake component parts, never wash them with water.

• Never depress brake pedal during removal and installation of brake hose because brake fluid may scatter.

Perform inspection before removal. Refer to Inspection.

Power switch OFF and disconnect CONSULT from DDL2 diagnosis connector.

Check that room lamps are turned OFF after closing all doors including back door, and then wait for 3 minutes or more at out side of Nissan Ariya vehicle.

Remove battery tray 1. Refer to Removal and Installation.

Drain brake fluid. Refer to Draining.

Disconnect the harness connectors from the engine control module (ECM).

Separate the brake tubes from the master cylinder part of the electrically-driven intelligent brake unit using a flare nut wrench.

Disconnect the harness connector from the brake fluid level switch.

Disconnect the harness connector from the electrically-driven intelligent brake unit.

Disconnect the harness connector from the stroke sensor as follows:Slide the connector lock (A) away (1) from the terminal side of the connector. While pressing the connector lock release button (2), pull the connector (B) away (3) from the stroke sensor part of the electrically-driven intelligent brake unit.

• Never crush threads of stud bolts of the electrically-driven intelligent brake unit. When installing diagonally, the dash panel may damage the threads.

• Never deform brake tube when installing electrically-driven intelligent brake unit.

• Never reuse clevis pin.

• Temporarily tighten the flare nut of brake tube by hand, and then tighten the flare nut to the specified tightening torque using flare nut torque wrench (commercial tool). Refer to Exploded View.

• Connect the harness connector to the electrically-driven intelligent brake unit as follows:

  1. With the connector lock unlocked, connect the harness connector (A) to the electrically-driven intelligent brake unit.

  2. Move the lever part (B) in the direction (C) until the lever part locks.

  3. Push in lock part (D) to lock the harness connector securely.

  

• Connect the harness connector to the stroke sensor part of the electrically-driven intelligent brake unit as follows:

  1. With connector lock unlocked, connect the harness connector (A) to the stroke sensor part of the electrically-driven intelligent brake unit in the direction (1).
