When installing the brake master cylinder sub-assembly onto the brake booster, or when removing the brake master cylinder sub-assembly from the brake booster, make sure that the brake master cylinder sub-assembly is kept horizontal or its tip faces downward (the piston faces upward) to prevent the master cylinder piston from falling off.
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 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.
