And I have never had any of those issues. In fact quite the contrary.the only benefits of my fathers car with SBC is
1) odd brake pedal feel,
2) odd noises from the module
3) a stupid penchant to stand on the brakes when you don't want it too (because the current drivers reaction time isn't as slow as many drivers they clearly thought needed help)
never had any of those issues on a car with conventional servo assistance
Pedal feel has always been excellent, it's never tried to stand on its nose (except once where I asked it to and it stopped in an amazingly short distance). As for the noise it doesn't bother me - it's just another feature and inaudible from inside .
Conversely when pressing on a few times in a conventional vehicle and left fort braking I've had the odd scary moment where servo assistance wasn't present when expected and was there when not expected!
I've also had a diaphragm in the servo fail and on one car a seal on the master cylinder allowed the servo to fill with brake fluid which then released vast clouds of white smoke out the exhaust as the fluid was sucked into the inlet manifold. I've also had a vacuum pump on a diesel car fail with no warning.
