I think the whole SBC failure thing is a bit overblown. Any part on a regular braking system can fail at any time causing loss if assist.
A fan belt can come off and power steering goes away.( Some cars have direct electric assist so that problem is minimized. )
A vacuum pump ( on a diesel ) can fail and power brake assist will go away, yet I don't see a wholesale panic by these car owners.

So does an SBC failure cause about the same braking effect as loss of vacuum on our older diesels? Or is it far worse? When the vacuum-pump failed on my Euro 300TD, it was disconcerting enough I didn't want to drive the car any more than was absolutely nessessary, but not so bad I needed BOTH feet to stop. I've repaired or replaced the vacuum pumps on both my W123s. The parts were pricey, but far less than $1500! Or even $750.
Happy Motoring, Mark
