If your $275.00 booster is working just accept it.
Anytime you are in the neighborhood like replacing the master cylinder
you should check for brake fluid in the passenger side of the booster.
Brake fluid leaks from leaky master cylinders can cause premature
failure.
To remove any fluid in there I use a turkey baster with a rubber
extension hose that can reach down into the booster and suck out any
fluid that is there.
If you want to be meticulous you can dampen a soft cotton cloth (used
cloth diaper or used T shirt) and swab out the interior then follow up
with some alcohol to get any sticky residue out of the tightest
crevasses.
