BRAKE FLUID BLEEDING

Tech Tips

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

Note


  • 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.


  1. REMOVE CENTER COWL TOP VENTILATOR LOUVER


    1. A010PMF

      Slide the hood to cowl top seal and detach the clip as shown in the illustration.

    2. A010O4Y

      Detach the 5 claws and remove the center cowl top ventilator louver.

  2. FILL RESERVOIR WITH BRAKE FLUID


    1. Fill the reservoir with brake fluid.

      Brake Fluid
      SAE J1704 or FMVSS No. 116 DOT 4

      Note

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

  3. BLEED BRAKE MASTER CYLINDER

    Note


    • If the master cylinder is reinstalled or if the reservoir becomes empty, bleed the master cylinder.

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


    1. A00OV3FE01

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

    2. A00OQDUE01

      Slowly depress the brake pedal and hold it.*1

    3. A00OVHRE01

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

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

    5. A00OV3FE01

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

      Torque:
      15 N*m  { 155 kgf*cm, 11 ft.*lbf }

      Note

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

  4. 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 brakes.


    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 then release the brake pedal.*2

    4. Repeat *1 and *2 until all the air in the fluid is completely bled out.

    5. Tighten the bleeder plug completely.

      Torque:
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

    6. Repeat the above procedure for each wheel to bleed the brake line.

  5. INSPECT FOR BRAKE FLUID LEAK

  6. INSPECT FLUID LEVEL


    1. A010LQYE01

      Check the fluid level.

      If the 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 J1704 or FMVSS No. 116 DOT 4

  7. INSTALL CENTER COWL TOP VENTILATOR LOUVER


    1. A010O4Y

      Attach the 5 claws to install the center cowl top ventilator louver.

    2. A010QERE01

      Push and attach the clip, and slide and attach the claw of the hood to cowl top seal as shown in the illustration.
