Using a union nut wrench (10 mm or 12 mm), disconnect the 2 brake lines from the master cylinder.

Slowly depress the brake pedal and hold it*1.

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

Repeat *1 and *2 3 or 4 times.

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

6. Repeat the above procedure for the rest of the wheels to bleed the brake lines.
   

Bleed the suction line according to "Step 2: Inhalation Line" on the Techstream display.

NOTICE:

1. Bleed the suction line by following the steps displayed on the Techstream.
   
2. 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 at the right front wheel or the right rear wheel and loosen the bleeder plug.
   

2. Operate the brake actuator assembly to bleed air using the Techstream*5.
   

   NOTICE:

   1. During this step, be sure to release the brake pedal.
      
   2. The actuator operation stops automatically in 4 seconds.
      

3. Check that the actuator operation has stopped by referring to the Techstream display, and tighten the bleeder plug*6.
   

4. Repeat *5 and *6 until all the air in the fluid is completely bled out.
   

5. Tighten the bleeder plug completely.
   

   Torque:

   Front bleeder plug:

   8.3 N*m{85 kgf*cm, 73 in.*lbf}

   2. After the operation is completed, the brake pedal goes down slightly. This is a normal phenomenon when the solenoid opens.
      
   3. During this procedure, the pedal seems heavy, but completely depress it so that the brake fluid comes out from the bleeder plug.
      
   4. Be sure to keep the brake pedal depressed. Never depress and release the pedal repeatedly.
      

4. Tighten the bleeder plug, and then release the brake pedal*8.

5. Tighten the bleeder plug completely.
   

   Torque:

   Front bleeder plug:

   8.3 N*m{85 kgf*cm, 73 in.*lbf}

Finish "Air Bleeding" on the Techstream, and then turn the Techstream off.

Disconnect the Techstream from the DLC3.

Turn the ignition switch off.

Check the fluid level.
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.
