BRAKE FLUID > REPLACEMENT

for Preparation Click here


HINT:
There are 2 ways of brake fluid replacement: using the intelligent tester or not using the intelligent tester.

NOTICE:
  1. Perform fluid replacement with park (P) selected and the parking brake applied.
  2. As brake fluid may overflow when replacing brake fluid, do not place the fluid can on the reservoir filler opening.
  3. Perform fluid replacement while maintaining the brake fluid level between the MIN/MAX level on the brake fluid reservoir.
  4. Replacing brake fluid will be difficult if the following occurs:
    1. The brake actuator hose (the hose between the brake booster pump and brake fluid reservoir) is lowered into the fluid and air enters the hose.
    2. During the fluid replacement procedure, air enters the brake booster pump while operating the pump motor.
  5. While performing fluid replacement, the accumulator pressure drop may cause a buzzer to sound. As there is no problem, continue with the fluid replacement.
  6. During fluid replacement, DTCs for pressure sensor malfunctions, etc. may be stored. After fluid replacement and if instructed in the procedures, clear the DTCs.
  7. Do not allow brake fluid to adhere to any painted surface such as the vehicle body. If brake fluid leaks onto any painted surface, immediately clean it off.



1. REPLACE BRAKE FLUID (for Using the intelligent tester)

NOTICE:
  1. Add brake fluid carefully and check that the reservoir level remains between the MIN and MAX lines.
  2. Do not stand the fluid can on the reservoir inlet. Doing so will cause brake fluid to overflow.



  1. Remove the center cowl top ventilator cover.



      C205662

    1. Slide the hood to cowl top seal and disengage the claw.

    2. Disengage the 2 claws and 3 guides, and remove the center cowl top ventilator cover.



  1. Replace brake fluid.



      C205665

    1. Remove the brake master cylinder reservoir filler cap assembly.

    2. Add brake fluid into the reservoir between MAX and MIN level on the brake fluid reservoir.

      Brake fluid:
      SAE J1703 or FMVSS No. 116 DOT3

    3. Connect the intelligent tester to the DLC3 and turn the power switch on (IG).

    4. Turn the intelligent tester on and enter the following menus: Chassis / ABS/VSC/TRC / Air Bleeding.

    5. Select the "Usual air bleeding" on the intelligent tester display, and replace the brake fluid following the instructions on the intelligent tester.

    6. After replacing brake fluid, tighten each bleeder plug.

      Torque:
      front bleeder plug:
      8.3 N*m{ 85 kgf*cm , 73 in.*lbf }
      rear bleeder plug:
      11 N*m{ 112 kgf*cm , 8 ft.*lbf }

  1. Clear the DTCs (Click here).

  1. Turn the intelligent tester off and turn the power switch off.

  1. Inspect for brake fluid leaks.

  1. Install the brake master cylinder reservoir filler cap.



  1. Install the center cowl top ventilator cover.



      C205663

    1. Engage the 2 claws and 3 guides to install the center cowl top ventilator cover.

    2. Slide the hood to cowl top seal to engage the claw.



2. REPLACE BRAKE FLUID (for not Using the intelligent tester)

NOTICE:
  1. Performing the following procedure will select ECB (Electronically Controlled Brake system) Invalid Mode without using the intelligent tester.
  2. ECB (Electronically Controlled Brake system) Invalid Mode allows the brake fluid to be replaced without using the intelligent tester.
  3. The brake warning light / yellow will blink to indicate when ECB (Electronically Controlled Brake system) Invalid Mode is selected.
  4. Be sure to inspect that the brake warning light / yellow is blinking while replacing the brake fluid.
  5. When one of the following conditions is met, ECB (Electronically Controlled Brake system) Invalid Mode is cancelled, and then the DTCs may be stored. So do not cancel the ECB (Electronically Controlled Brake system) Invalid Mode while replacing brake fluid.
    The shift lever is used to select from P to any other position.
    Turn the power switch on (READY).
    Turn the power switch off.
    The parking brake is released.
    The vehicle velocity is not 0 km/h (0 mph).
  6. Do not rotate the brake disc while ECB (Electronically Controlled Brake system) Invalid Mode is selected.
  7. When replacing the brake fluid from the brake line, do not depress the brake pedal to operate the brake booster pump more than 100 seconds. If the brake booster pump is operated more than 100 seconds, ECB (Electronically Controlled Brake system) Invalid Mode is automatically finished and the DTCs may be stored.
  8. Add brake fluid carefully and check that the reservoir level remains between the MIN and MAX lines.
  9. Do not stand the fluid can on the reservoir inlet. Doing so will cause brake fluid to overflow.

  1. Remove 4 wheels.



  1. Select ECB (Electronically Controlled Brake system) Invalid Mode.

    1. Perform the procedure listed below in 1 minute.

      1. Turn the power switch on (IG) with park (P) selected and parking brake applied.
      2. Select N and then depress the brake pedal more than 8 times in 5 seconds.
      3. Push the P position switch and then depress the brake pedal more than 8 times in 5 seconds.
      4. Select N and then depress the brake pedal more than 8 times in 5 seconds.
      5. Push the P position switch.
