BRAKE FLUID BLEEDING

Note


  • 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 wash it off.

  • Before bleeding the brake system, confirm that the reservoir located above the master cylinder assembly is filled with brake fluid.

  • If bleeding is performed with the engine running or the engine switch on (IG), DTC C1441 will be stored. Make sure to clear the DTCs when work is complete.

Tech Tips

If any component of the brake system is removed and reinstalled, or if air in the brake lines is suspected, bleed the brake system.


  1. FILL RESERVOIR WITH BRAKE FLUID


    1. A01EJ3G

      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.

      • 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 problem.

  2. BLEED BRAKE MASTER CYLINDER

    Note


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

    • Be sure to clean your hands before bleeding from master cylinder to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problem.

    Tech Tips

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


    1. A01EL46

      Using a union nut wrench, disconnect the 2 brake tubes from the brake master cylinder assembly.

    2. A01ELBP

      Slowly depress the brake pedal and hold it down.

    3. A01EM39

      Cover the 2 tube holes with your fingers and release the brake pedal.

    4. Uncover the holes, slowly depress the brake pedal and hold it down. While holding down the brake pedal, cover the tube holes again. Repeat this step 3 or 4 times.

    5. A01EL46

      Using a union nut wrench, connect the 2 brake tubes to the brake master cylinder assembly.

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

      Note


      • Do not bend or damage the brake lines.

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

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

      • Use the formula to calculate special torque values for situations where 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.


    1. Connect a vinyl tube to the bleeder plug.

    2. Depress the brake pedal several times, and while holding down the brake pedal, loosen the bleeder plug*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 the new brake fluid comes out.

    5. Tighten the bleeder plug completely.

      Torque:
      13 N*m  { 133 kgf*cm, 10 ft.*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 FLUID LEVEL IN RESERVOIR


    1. A01EKWYE01
      Text in Illustration
      *1 MAX Line
      *2 MIN Line

      Check the fluid level.

      Tech Tips

      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
