Brake System Air Bleeding

In case of brake caliper and brake line replacement, perform the air bleeding procedures.

NOTE:
  • Do not reuse the drained fluid.
  • Always use genuine DOT4 brake Fluid. Using a non-genuine DOT4 brake fluid can cause corrosion and decrease the life of the system.
  • Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.
  • Do not spill brake fluid on the vehicle, it may damage the paint; if brake fluid does contact the paint, wash it off immediately with water.
  • When bleeding air, make sure the brake fluid is above 10 mm (0.39 in) starting from the "MIN" line.
  • To remove the reservoir tank cap to refill the brake fluid, always close the air shut-off valve of the SST.
  1. Disconnect the negative (-) battery terminal to turn off IEB ECU.
  2. Refill the reservoir to MAX (upper) level line.

    Brake fluid:  DOT 4

  3. Set the air bleeding tool (SST: 09580-3D100) and the cap of SST (0K585-E8100) to reservoir tank and make pressure (3 bar) to it.
  4. Lock the bleed screw after stepping on brake pedal 10 - 20 times in condition of break fluid has been drained out for 10 seconds after opening each bleed screws (A).

    Tightening torque: 

    Front air bleeding screw (Mando 18 inch): 13.7 - 19.6 N.m (1.4 - 2.0 kgf.m, 10.1 - 14.5 lb-ft)

    Front air bleeding screw (Continental 19 inch): 11.8 - 17.7 N.m (1.2 - 1.8 kgf.m, 8.7 - 13.0 lb-ft)

    Rear air bleeding screw: 6.9 - 12.7 N.m (0.7 - 1.3 kgf.m, 5.1 - 9.4 lb-ft)

    NOTE:
    • To improve the work efficiency bleed the air in the following order: FR → FL → RL → RR.
    • If the brake fluid goes below 'MIN' while working, remove the pressure feeder and mount the pressure feeder after filling the brake fluid in the reservoir.
    • Repeat the procedure for wheel in the sequence shown below until air bubbles no longer appear in the fluid.
    • Be careful not to open the bleed screw too much as the air may get inside the pipe.

  5. Remove the air bleeding tool carefully.
  6. Refill the reservoir to "MAX" level line.
  7. Connect the negative (-) battery terminal to turn on IEB ECU.
  8. Repeat the above procedure if air leaking process has not done properly after the procedure is done.
