   NOTICE:

   Tighten the 2 nuts in the order shown in the illustration.

2. Install the wire harness clamp.
   

HINT:

Refer to the procedure from Install Front Cross Member Sub-assembly (Click here).

HINT:

Refer to the procedure from Install Brake Booster with Master Cylinder assembly (Click here).

1. Disengage the clamp.
   

2. Remove the 2 nuts and separate the brake master cylinder reservoir with bracket.
   

NOTICE:

Make sure to bleed the air from the No. 1 brake actuator tube. If the air remains in the No. 1 brake actuator tube, the air enters into the brake booster pump assembly and it may cause the brake booster pump assembly to be damaged.

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

2. Add brake fluid into the reservoir between the MAX and MIN level on the brake fluid reservoir.
   

   Brake Fluid:

   SAE J1703 or FMVSS No. 116 DOT3
   

3. Install the brake master cylinder reservoir filler cap assembly.
   

4. Remove the nut, disengage the clamp and separate the No. 1 brake actuator tube from the vehicle body.
   

5. Lift up the brake master cylinder reservoir with bracket as far as possible.
   

   NOTICE:

   Do not spill the brake fluid.

6. While holding the brake master cylinder reservoir with bracket, twist and hold the No. 1 brake actuator tube 90° toward the vehicle front, and wait at 5 seconds.*1
   

   NOTICE:

   Do not damage the hoses.

   HINT:

   Keeping the No. 1 brake actuator tube twisted causes the remaining air inside the No. 1 brake actuator tube to be expelled to the brake master cylinder reservoir assembly.

7. Return the No. 1 brake actuator tube to its original state.
   

8. While holding the brake master cylinder reservoir with bracket, twist and hold the No. 1 brake actuator tube 90° toward the vehicle rear, and wait at 5 seconds.
   

   NOTICE:

   Do not damage the hoses.

   HINT:

   Keeping the No. 1 brake actuator tube twisted causes the remaining air inside the No. 1 brake actuator tube to be expelled to the brake master cylinder reservoir assembly.

9. Return the No. 1 brake actuator tube to its original state.*2
   

10. Repeat steps *1 to *2, 5 times.
    

11. While holding the brake master cylinder reservoir with bracket, pinch the brake actuator hose 10 times with your fingers.
    

    NOTICE:

    Do not use pliers or similar to pinch the brake actuator hose. Doing so may cause damage to the brake actuator hose. Make sure to use your fingers.

12. Repeat steps *1 to *2, 5 times again, and check that air is not expelled from the No. 1 brake actuator tube.
    

13. Engage the clamp and install the No. 1 brake actuator tube with the nut.
    

    Torque:

    8.4 N*m{ 85 kgf*cm , 74 in.*lbf }
