BRAKE FLUID REPLACEMENT

CAUTION / NOTICE / HINT

Note


  • Perform fluid replacement with the shift lever in P and the parking brake applied.

  • As brake fluid may overflow when replacing brake fluid, do not stand the fluid can on the reservoir inlet.

  • Perform fluid replacement while maintaining the brake fluid level between the MIN and MAX lines on the brake fluid reservoir.

  • Replacing brake fluid will be difficult if the following occurs:


    1. The brake actuator hose (the hose between the brake booster pump assembly and brake fluid reservoir) is higher than the fluid level and air enters the hose.

    2. During the fluid replacement procedure, air enters the brake booster pump assembly while the pump motor is operating.

  • While performing fluid replacement, the accumulator pressure drop may cause a buzzer to sound. As there is no problem, continue with the fluid replacement.

  • During fluid replacement, DTCs for pressure sensor malfunctions, etc. may be stored. After fluid replacement and if instructed in the procedures, clear the DTCs.

  • 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.

Tech Tips

There are 2 ways of brake fluid replacement: using the GTS or not using the GTS.

PROCEDURE


  1. REMOVE CENTER COWL TOP VENTILATOR LOUVER (for LHD)

    A01UZAG

    1. Disengage the 2 clips and slide the hood to cowl top seal as shown in the illustration.

    2. A01V25W

      Disengage the 2 claws to separate the washer hose joint.

      Note

      To prevent washer fluid from contaminating the brake master cylinder reservoir, do not separate the washer hose.

    3. Disengage the 5 claws and 3 guides to remove the center cowl top ventilator louver.

  2. REMOVE CENTER COWL TOP VENTILATOR LOUVER (for RHD)

    A01V265

    1. Disengage the clip and slide the hood to cowl top seal as shown in the illustration.

    2. A01V0EA

      Disengage the 2 claws to separate the washer hose joint.

      Note

      To prevent washer fluid from contaminating the brake master cylinder reservoir, do not separate the washer hose.

    3. Disengage the 4 claws and 3 guides to remove the center cowl top ventilator louver.

  3. REPLACE BRAKE FLUID (when Using the GTS)

    Note


    • Add brake fluid carefully and check that the fluid level remains between the MIN and MAX lines on the brake fluid reservoir.

    • Do not stand the fluid can on the reservoir inlet. Doing so will cause brake fluid to overflow.


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

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

      Brake fluid
      SAE J1704 or FMVSS No. 116 DOT4

      Note

      Do not remove the filter from the brake master cylinder reservoir and be sure to fill with new brake fluid to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.

    3. Connect the GTS to the DLC3 and turn the ignition switch to ON (IG).

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

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

      Tech Tips

      It is not necessary to disconnect the reservoir level switch connector.

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

      Torque:
      Front bleeder plug (w/ Anti-lattle Spring)
      17 N*m  { 173 kgf*cm, 13 ft.*lbf }
      Front bleeder plug (w/o Anti-lattle Spring)
      8.3 N*m  { 85 kgf*cm, 73 in.*lbf }
      Rear bleeder plug
      14 N*m  { 143 kgf*cm, 10 ft.*lbf }

    7. Install the brake master cylinder reservoir filler cap assembly.

    8. Clear the DTCs Click here.

    9. Turn the GTS off and turn the ignition switch off.

    10. Inspect for brake fluid leaks.

  4. REPLACE BRAKE FLUID (when Not Using the GTS)

    Note


    • Performing the following procedure will enable ECB* Invalid Mode without using the GTS.

    • ECB* Invalid Mode allows the brake fluid to be replaced without using the GTS.

    • The brake warning light / yellow will blink to indicate when ECB* Invalid Mode is enabled.

    • Be sure to inspect that the brake warning light / yellow is blinking while replacing the brake fluid.

    • When one of the following conditions is met, ECB* Invalid Mode is cancelled, and DTCs may be stored. Do not cancel ECB* Invalid Mode while replacing brake fluid.

      The shift lever is moved to any other position from P.
      The ignition switch is turned ON (READY).
      The ignition switch is turned off.
      The parking brake is released.
      The vehicle speed is not 0 km/h (0 mph).

    • Do not rotate the front disc or rear drum while ECB* Invalid Mode is enabled. If the front disc or rear drum is rotated, ECB* Invalid Mode may be cancelled.

    • When replacing the brake fluid from the brake line, do not depress the brake pedal to operate the brake booster pump assembly for more than 100 seconds. If the brake booster pump assembly is operated for more than 100 seconds, ECB* Invalid Mode is automatically finished and DTCs may be stored.

    • Add brake fluid carefully and check that the fluid level remains between the MIN and MAX lines on the brake fluid reservoir.

    • Do not stand the fluid can on the reservoir inlet. Doing so will cause brake fluid to overflow.
