      Torque: 13 N*m (127 kgf*cm, 9 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 matter to contaminate the master cylinder piston. If foreign matter gets on the piston, remove it by using 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.
  3. CONNECT BRAKE LINE 
    1. Using a union nut wrench, connect the 2 brake lines to the brake master cylinder sub-assembly.
