BRAKE FLUID BLEEDING

Note


  • Move the shift lever to P and apply the parking brake before bleeding the brakes.

  • Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brakes.

  • If brake fluid leaks onto any painted surface, immediately wash it off.

  • Do not operate the brake actuator assembly while air is in the brake system or in the brake master cylinder sub-assembly. Doing so may cause air to enter the brake actuator assembly.

  • If bleeding the brake actuator assembly is difficult due to air in the brake actuator assembly, replace it with a new one.

Tech Tips

If any work is performed on the brake system or if air in the brake lines is suspected, bleed the air from the brake system.


  1. FILL RESERVOIR WITH BRAKE FLUID


    1. A01EWEL

      Remove the brake master cylinder reservoir filler cap.

    2. Fill the reservoir with brake fluid.

      Brake Fluid
      SAE J1703 or FMVSS No. 116 DOT 3

      Note

      Make sure that there is sufficient brake fluid in the reservoir.

  2. BLEED BRAKE MASTER CYLINDER

    Note

    To prevent brake fluid from damaging painted surfaces, cover any surrounding parts with a piece of cloth.

    Tech Tips

    If the brake master cylinder sub-assembly is reinstalled or runs out of brake fluid, bleed the brake master cylinder sub-assembly.


    1. A01EXE0

      Using a union nut wrench, disconnect the 2 brake lines from the brake master cylinder sub-assembly.

    2. A01EVD0

      Slowly depress the brake pedal and hold it.*1

    3. A01EXJY

      Cover the 2 outer holes with fingers, and release the brake pedal.*2

    4. Repeat steps *1 and *2, 3 or 4 times.

    5. A01EXE0

      Using a union nut wrench, connect the 2 brake lines to the brake master cylinder sub-assembly.

      Torque:
      20 N*m  { 199 kgf*cm, 14 ft.*lbf }

      Note


      • Do not bend or damage the brake lines.

      • Do not allow brake lines to twist and interfere with other parts or vehicle body during tightening.

      • Do not allow any foreign matter such as dirt or dust to enter the brake lines.

      • Use the formula to calculate special torque values for situations where the union nut wrench is combined with a torque wrench Click here.

  3. BLEED BRAKE LINE

    Note


    • Bleed the brake line of the wheel farthest from the master cylinder first.

    • Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brake lines.


    1. Connect a vinyl tube to the bleeder plug.

    2. Depress the brake pedal several times, and then loosen the bleeder plug with the pedal depressed.*1

    3. When fluid stops coming out, tighten the bleeder plug, and release the brake pedal.*2

    4. Repeat steps *1 and *2 until all the air in the brake fluid is completely bled out and a new brake fluid comes out.

    5. Tighten the bleeder plug completely.

      Torque:
      8.3 N*m  { 85 kgf*cm, 73 in.*lbf }

    6. Repeat the above steps to replace the brake fluid of the brake lines for each wheel.

  4. INSPECT FOR BRAKE FLUID LEAK

  5. INSPECT BRAKE FLUID LEVEL IN RESERVOIR


    1. A01EU6TE01
      Text in Illustration
      *a MAX Line
      *b MIN Line

      Check the fluid level.

      If brake fluid level is lower than the MIN line, check for leaks and inspect the disc brake pads. If necessary, refill the reservoir with brake fluid to the MAX line after repair or replacement.

      Brake Fluid
      SAE J1703 or FMVSS No. 116 DOT 3

      Note

      If using a dropper to adjust the fluid amount, make sure that the dropper has not been used with mineral oils, water or deteriorated brake fluid. Sealed areas may deteriorate and lead to fluid leaks, or the fluid may deteriorate and lead to decreased efficiency.
