Brake booster shelf life?

[LT1 OLDS]

About 10 years ago I bought a power brake booster and master cylinder from Master Power. It has been sitting on a shelf in the garage in the original box watching project cars come and go. I'm now ready to use it. Is it still good?:confused:

Should be. The only thing to go bad is the diaphragm, as long as you didn't expose it to extreme heat or oil and solvents it should be fine.

Thanks. I guess I'll give a shot and see what happens
