Brake booster ruined???????

[TexasJimmy]

I need some help.

I am adding brake fluid to the small chamber in the master cylinder often. No signs of leaks anywhere.

I unbolted the master cylinder from the booster and fluid ran out.

Questions:
1. Can the fluid be sucked thru the booster vacuum line and burned in the engine(loss of fluid)? If true, any thing I need to do to lines...ect...that came in contact with the fluid?
2. Can I replace the master cylinder and leave the booster alone? Will the brake fluid in the booster harm the booster.

Thanks in advance..
