I am not sure the average consumer appreciates how revolutionary the braking system of the modern hybrid is. For 100 years the only way to stop a car was to rub metal and ceramic parts together, generating heat, noise, and brake dust. It is all parasitic waste. Sure it is implemented a bit better than on Fred Flintstone's car, but it is still essentially a crude system unchanged for more than a century.

On our hybrids, breaking doesn't carry with it all that penalty.

Since I got interested I have been looking for documents on details about how the FEH braking system is designed. Does anyone have a detailed schematic? Is the brake pedal linked directly to a master cylinder or is that driven in another way, and what role/dependence does the computer play?
I note that the gas pedal seems to be all fly-by-wire, but I don't think the brake is. Is this correct?

Any answers appreciated?
