      • SST: 49U043004A, 49U043005, 49U043006 
    4. Bleed the brake line and the SSTs of air. Bleed the air form the SSTs using bleeder screw A.
    5. Connect the Techstream to the DLC-2.
    6. Select the "BRK_F_P_R" PID.
    7. Start the engine.
    8. Depress the brake pedal, and confirm that the fluid pressure value of the SST (gauge) and the value shown on the Techstream are equal.
      • If the fluid pressures are different, replace the brake actuator.

        Refer to REMOVAL 

    9. After the inspection, remove the SSTs, install the brake hose and brake pipe to the original positions.

      Refer to REMOVAL

    10. Bleed the air from the brake line.
