   NOTE:

   • Do not carry the brake booster pump assembly by the parts shown in bold (*1, *2 and *3) in the illustration.
   • Do not drop the brake booster pump assembly when carrying it.
   • Be careful not to allow any brake fluid to enter the connector.
   • When installing the brake booster pump assembly to the brake actuator bracket assembly, confirm that the 2 brake booster pump collars (*6) and 2 brake booster pump bushings (*5) are installed on the brake booster pump assembly.
   • Do not remove the hole plugs before installing a new brake booster pump assembly because the brake booster pump assembly is filled with brake fluid.
2. Install the brake actuator case collar (*7), brake booster pump bushing (*8) and brake booster pump assembly to the brake actuator bracket assembly with the nut.

   Torque: 5.4 N*m (55 kgf*cm, 48 in.*lbf) 

3. Engage the wire harness clamp to the brake actuator bracket assembly.

1. Install the No. 2 brake actuator hose to the brake booster pump assembly with the clip.

4. Install the bolt to secure the connector box to the brake actuator bracket assembly.

   Torque: 8.0 N*m (82 kgf*cm, 71 in.*lbf) 

5. Connect the 2 connectors to the brake booster pump assembly.

1. Using a union nut wrench, connect the front No. 1 brake tube to the brake booster pump assembly.

   Torque: 15 N*m (155 kgf*cm, 11 ft.*lbf) 

   NOTE:

   Use the formula to calculate special torque values for situations where the union nut wrench is combined with a torque wrench. Refer to PRECAUTION [08/2013 - ] .

1. Connect the No. 2 brake actuator hose to the No. 1 brake actuator tube with the clip.

   NOTE:

   • Match the identification mark of the No. 2 brake actuator hose and No. 1 brake actuator tube.
   • Install the clip within the range shown in the illustration.

1. Remove the vinyl tape from the openings of the disconnected parts.
2. Sufficiently apply compressor oil to a new O-ring, the fitting surface of the suction pipe sub-assembly and air conditioning unit.

   Compressor oil

   ND-OIL 11 or equivalent

   NOTE:

   Do not use any compressor oil other than ND-OIL 11 or equivalent. If any compressor oil other than ND-OIL 11 or equivalent is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.

3. Install the O-ring to the suction pipe sub-assembly.
   NOTE:

   Keep the O-ring and O-ring fitting surfaces free from dirt or any foreign matter.

4. Insert the suction pipe sub-assembly to the air conditioning unit.

   NOTE:

   • Insert the pipe joint into the fitting hole securely.
   • Do not deform the piping.
   • Do not damage the plastic clamp.

1. Remove the vinyl tape from the openings of the disconnected parts.
2. Sufficiently apply compressor oil to a new O-ring, the fitting surface of the air conditioning tube and accessory assembly and air conditioning unit.

   NOTE:

   Do not use any compressor oil other than ND-OIL 11 or equivalent. If any compressor oil other than ND-OIL 11 or equivalent is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.

3. Install the O-ring to the air conditioning tube and accessory assembly.
   NOTE:

   Keep the O-ring and O-ring fitting surface free from dirt or any foreign matter.

4. Insert the air conditioning tube and accessory assembly to the air conditioning unit.
