      NOTE:
      • The brake master cylinder sub-assembly requires careful handling. Do not allow the brake master cylinder sub-assembly to receive any impact, such as from being dropped. Do not reuse a brake master cylinder sub-assembly that has been dropped.
      • Do not hold the brake master cylinder sub-assembly by the master cylinder piston. Hold the brake master cylinder sub-assembly by its body or its reservoir when carrying it.
      • Do not pull out the master cylinder piston.
      • Do not strike or pinch the master cylinder piston, or cause any damage to the master cylinder piston by any other means.
      • When installing the brake master cylinder sub-assembly to the brake booster assembly, or when removing the brake master cylinder sub-assembly from the brake booster assembly, make sure that the brake master cylinder sub-assembly is kept horizontal or with its tip facing downward (the master cylinder piston is facing upward) to prevent the master cylinder piston from falling out.
      • Do not allow any foreign matter to contaminate the master cylinder piston. If any foreign matter gets on the master cylinder piston, remove it by using a piece of new and dry cloth. Do not use water or detergent. Then apply an even layer of lithium soap base glycol grease around the circumference (sliding part) of the master cylinder piston.
