BRAKE FLUID(w/o VSC) BLEEDING

CAUTION / NOTICE / HINT

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


  • for Manual Transmission:

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

  • for Automatic Transmission:

    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.

  • When bleeding air, select the suitable procedure listed below.

PROCEDURE


  1. BLEED BRAKE LINE


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

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

      Brake fluid
      except TSAM Made
      SAE J1703 or FMVSS No. 116 DOT 3
      for TSAM Made
      SAE J1704 or FMVSS No. 116 DOT 4

      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. Loosen the bleeder plug of the front disc brake cylinder RH.

    4. Repeatedly depress the brake pedal and bleed the air from the bleeder plug of the front disc brake cylinder RH.

      Note

      Add fluid as necessary so that the fluid in the reservoir does not decrease below the MIN level.

    5. After air is completely bled out, tighten the bleeder plug while depressing the brake pedal.

      Torque:
      10.8 N*m  { 110 kgf*cm, 8 ft.*lbf }

    6. Bleed the air from the bleeder plug of the front disc brake cylinder LH using the same procedure as for the RH side.

    7. Loosen the bleeder plug of the rear brake cylinder RH.

    8. Repeatedly depress the brake pedal and bleed the air from the bleeder plug of the rear brake cylinder RH.

      Note

      Add fluid as necessary so that the fluid in the reservoir does not decrease below the MIN level.

    9. After air is completely bled out, tighten the bleeder plug while depressing the brake pedal.

      Torque:
      except TMEE (AAV) Made
      10.8 N*m  { 110 kgf*cm, 8 ft.*lbf }
      for TMEE (AAV) Made
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

    10. Bleed the air from the bleeder plug of the rear brake cylinder LH using the same procedure as for the RH side.

    11. Inspect for brake fluid leaks.

    12. Inspect brake fluid level in reservoir.

  2. BLEED BRAKE SYSTEM

    Note

    Be sure to clean your hands before bleeding from the 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 problems.


    1. Bleed the brake master cylinder.


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

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

        Brake fluid
        except TSAM Made
        SAE J1703 or FMVSS No. 116 DOT 3
        for TSAM Made
        SAE J1704 or FMVSS No. 116 DOT 4

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

        Note


        • Do not kink or damage the brake lines.

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

      4. Slowly depress and hold the brake pedal.*1

      5. Block the outer holes with your fingers, and release the pedal.*2

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

      7. B003N95C03
        *a Torque Wrench Fulcrum Length

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

        Torque:
        Specified tightening torque
        15.2 N*m  { 155 kgf*cm, 11 ft.*lbf }

        Tech Tips


        • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
