Near as I can tell, it hasn't been proven that if the service life counter hits zero while in flight, the system will leave you without primary braking force.
The SBC was tested and determined to have X brake applications before failure. Adding in a safety margin + variability of mass production and you end up with some % of X where the system goes to a white early warning. After more brake applications the system goes red to force replacement of the SBC to minimize the chance of a sudden failure.
It makes absolutely no sense for a red end of service life warning to shut the system down while in flight as end of service life is a safety strategy. Sure, it may shut down after a key off cycle but it should never do so in flight. A strategy of shutting down in flight when the service life counter hits zero wouldn't even make if past an engineering intern.
Now, if a part actually fails, the system might go red and quit working but this isn't the same as a service life counter.
The SBC issue has been discussed in the past.
