Possible- not probable. It also means it may NOT be possible unless you apply the full 500n of force; you may get NO braking at all. More than a few owners online have stated there was no warning whatsoever when their SBC brakes failed. Why on earth would you try to deny that? What do you have to gain?

I don't know who you are responding to but, I'll pick it up.
You make it sound like a binary choice.
If < 500 N force then braking = 0G
If >= 500 N force then braking = 0.3G
Based on the hydraulic diagram, that isn't true. Backup braking force is proportional to foot force as this system does not have a pressure reducing or sequencing valve.
The "making it possible" statement pertains to the backup unit ( Master cylinder ) in the sense that " The operating unit ( 1 ) exists as a backup in the event of a brake by wire system failure that inhibits the computers ability to control the solenoids. "
