Brake Master Cylinder: Installation

INSPECT AND ADJUST BRAKE BOOSTER PUSH ROD (See INSPECTION )
INSTALL BRAKE MASTER CYLINDER SUB-ASSEMBLY
1. Install a new O-ring to the brake master cylinder sub-assembly.
2. Install the brake master cylinder sub-assembly to the brake booster assembly with the 2 nuts.
  Torque: 13 N*m (132 kgf*cm, 10 ft.*lbf)
  NOTE:
  - The master cylinder requires careful handling. Do not allow the master cylinder to receive any impact, such as from being dropped. Do not reuse a master cylinder that has been dropped.
  - Do not strike or pinch the master cylinder piston, and do not cause any damage to the master cylinder piston by any other means.
  - When installing the master cylinder to the brake booster, or when removing the master cylinder from the brake booster, make sure that the master cylinder is kept horizontal or its tip faces downward (the piston faces upward) to prevent the master cylinder piston from falling out.
  - Do not allow any foreign objects to contaminate the master cylinder piston. If a foreign object gets on the piston, remove it by using a shop rag or a piece of cloth and then apply an even layer of lithium soap based glycol grease around the circumference (sliding part) of the piston.
  - Do not use any other type of grease or fluid.

CONNECT BRAKE LINE
1. Using a union nut wrench (12 mm), connect the 2 brake lines to the brake master cylinder sub-assembly.
  Torque: without union nut wrench
  
  20 N*m (204 kgf*cm, 15 ft.*lbf)
  
  with union nut wrench
  
  18 N*m (184 kgf*cm, 13 ft.*lbf)
  NOTE:
  - Use a torque wrench with a fulcrum length of 250 mm (9.84 in.).
  - This torque value is effective when the union nut wrench is parallel to the torque wrench.
