Brake System Bleeding

Print


NOTE
After bleeding the air from the brake system, if the height or feel of the brake pedal cannot be obtained, perform air bleeding in the brake actuator assembly with the Scan Tool by following the procedures below.

  1. Depress the brake pedal more than 20 times with the engine off.
  2.  
  3. Connect the Scan Tool to the DLC3, and turn the ignition switch to the ON position.
  4.  
  5. Select "AIR BLEEDING" on the Scan Tool.
  6.  
  7. Bleed the air out of the brake line as usual when "Step 1: Increase" appears on the Scan Tool display.
    NOTE
    Bleed the air by following the steps displayed on the Scan Tool. Make sure that the brake fluid in the master cylinder reservoir tank does not become empty.

    1. Connect the vinyl tube to either one of the bleeder plugs.
    2.  
    3. Depress the brake pedal several times, then loosen the bleeder plug connected to the vinyl tube with the pedal depressed.
    4.  
    5. When fluid stops coming out, tighten the bleeder plug and release the brake pedal.
    6.  
    7. Repeat this procedure until all air in the fluid is completely bled out.
    8.  
    9. Tighten the bleeder plug completely.
    10.  
    11. Repeat the above procedures for each wheel to bleed the air out of the brake line.
    12.  

  8.  
  9. Bleed the air out of the suction line when "Step 2: Inhalation" appears on the Scan Tool display.
    NOTE
    Bleed the air by following the steps displayed on the Scan Tool. Make sure that the brake fluid in the master cylinder reservoir tank does not become empty.

    1. Connect the vinyl tube to the bleeder plug at the right front wheel or the right rear wheel and loosen the bleeder plug.
    2.  
    3. Operate the brake actuator assembly to bleed the air using the Scan Tool.
      NOTE
      At this time, be sure to release the brake pedal.


      NOTE
      This operation stops automatically after 4 seconds.

    4.  
    5. Check if the operation has stopped by referring to the Scan Tool display.
    6.  
    7. Repeat this until all air in the fluid is completely bled out.
    8.  
    9. Tighten the bleeder plug.
    10.  
    11. Repeat the above procedures for the other wheels to bleed the air out of the brake line.
    12.  

  10.  
  11. Bleed the air out of the pressure reduction line when "Step 3: Decrease" appears on the Scan Tool display.
    NOTE
    Bleed the air by following the steps displayed on the Scan Tool. Make sure that the brake fluid in the master cylinder reservoir tank does not become empty.

    1. Connect a vinyl tube to either one of the bleeder plugs.
    2.  
    3. Loosen the bleeder plug.
    4.  
    5. Using the Scan Tool, operate the brake actuator assembly, completely depress the brake pedal and keep it.
      NOTE
      During this procedure, the pedal will feel heavy, but completely depress it so that the brake fluid comes out from the bleeder plug. Be sure to keep depressing the brake pedal. Do not depress and release the pedal repeatedly.


      NOTE
      The operation stops automatically after 4 seconds. When performing this procedure continuously, set an interval of at least 20 seconds. When the operation is complete, the brake pedal goes down slightly. This is a normal phenomenon caused when the solenoid opens.

    6.  
    7. Tighten the bleeder plug, then release the brake pedal.
    8.  
    9. Repeat this until all the air in the fluid is completely bled out.
    10.  
    11. Tighten the bleeder plug.
    12.  
    13. Repeat the above procedures for the other wheels to bleed the air out of the brake line.
    14.  

  12.  
  13. Bleed the air out of the brake line as usual again when "Step 4: Increase" appears on the Scan Tool display.
    NOTE
    Bleed the air by following the steps displayed on the Scan Tool. Make sure that the brake fluid in the master cylinder reservoir tank does not become empty.

    1. Connect the vinyl tube to either one of the bleeder plugs.
    2.  
    3. Depress the brake pedal several times, then loosen the bleeder plug connected to the vinyl tube with the pedal depressed.
    4.  
    5. When fluid stops coming out, tighten the bleeder plug, then release the brake pedal.
    6.  
    7. Repeat this until all the air in the fluid is completely bled out.
    8.  
    9. Tighten the bleeder plug.
    10.  
    11. Repeat the above procedures for the other wheels to bleed the air out of the brake line.
    12.  
    13. Make sure that the air bleeding is complete by referring to the Scan Tool display.
    14.  
    15. Check the fluid level and add fluid if necessary.
