Brembo’s new “Sensify” braking system takes that one step further, eliminating the hydraulic system entirely and relying instead purely on electronic brake-by-wire and electric motors
OK now show us a scenario where the vehicle is badly damaged in a traffic collision, the electrical system is compromised, (possibly even on fire) and show me the vehicle slowing to a stop safely with no electrical systems functioning what-so-ever or GET OUT OF HERE WITH THIS INSANITY
‘Classic’ cars can be heavy enough to boil brake fluid in heavy breaking situations. Once the fluid boils you lose all breaking power at once on all 4 wheels.
Can also boil break fluid if a wheel bearing fails while driving( repair shop packed it too tight)
Also the magic stop juice comes out if you panic stomp on the breaks while headed down an icy hill.
I’m with you, but playing devil’s advocate… A hydraulic brake line can be damaged in an accident as well. Simple brakes with a proportioning valve or similar mechanism likey doubles your redundancy for most failures of downstream brake components but that’s not guaranteed.
It does say electric motors are a part of the system which could be like the electronic parking brakes in many modern cars. Maybe they default to a closed/braking condition if power is lost?
I will not be the one risking my life or my family’s life or the lives of other families to be an early adopter of this tech, but it could work with rigorous engineering and testing.
Oh I’m with you there, but hydraulic hard lines and high pressure brake lines are thousands of times more rugged than electrical wires and cannot be rendered useless by software mistakes or operating system crashes.
The ABS controller, computer functions of a regular car can fail catastrophically, the vacuum system can be breached and made useless, but the hydraulic brake pedal is still capable of slowing a car to a stop.
Fail secure sounds good but now you also need to consider how quickly the brakes engage. Don’t want some random electrical hiccup locking up your brakes mid curve while you’re three-wide doing 70 on an interstate. Slowly draining capacitors or whatever to gradually engage them might be an option. Then you also, preferably, need some means of physically disengaging them. Otherwise you’re gonna get disabled vehicles in the middle of roadways that have to be dragged up onto flatbeds or the side of the road because the wheels won’t roll without restoring brake power first.

I have had hydraulic brakes fail more than while driving. They can fail even when the lines are fully intact.
That sounds more like a lack of maintenance in my experience, but I wouldn’t want to be where you were sitting when that happened.

IANAE, so just spitballing, but… passive braking? Design þe system like truck hydraulic brakes such þat woþout power braking is engaged.
