It's a user-operated fallback braking device coupled with a valve that lowers tire pressure. In cases of emergency braking, the tires will go flat to help slow the car down if the braking system fails.
If the drive-by-wire system fails, the results can be catastrophic. Ford recently had problems with six Mach-E models in Norway. The regenerative braking system kept on recuperating energy, overheating the batteries.
To work around this problem, Daimler came up with the new fallback system. It only comes into play when the actuator master unit fails or even has a simple error. In this case, the brake pedal is connected to the fallback unit, which is a basic friction system. The main new feature is the air release valve, which can reduce tire pressure.

Clearly, that would be trump’s fault.

A nice turn of phrase.
I might steal it if I can remember it when needed.
Actually for many years there was a front circuit and a back circuit. It was not until later that they went diagonal.

Sad but true.
Flat front tires make the car very hard to maneuver.
—”By the time it stops you the car will be on fire. Friction is a real thing.”
They seldom catch fire because as the PSI drops the rim seal is lost.
Soon after the rubber tire departs the wheel for parts unknown.
As the bottom of the car is sliding on the pavement.
—”Flat front tires make the car very hard to maneuver.”
True, but if the algorithm decides you are possibly impaired they will flatten your tires and lock you in; until you can pass the sobriety test. Better keep a compressor in the trunk. And hope you do not lose the rim seal.

You may want to add a titanium scrape plate.
Best at night to show you are a real scratcher.
Yes, some go with magnesium.
Your call.
I lost brakes in a snow storm. Side swiped snow banks to slow down, and minimal damage. Lost brakes another time (macadam flipped up ripping out brake hose) and just coasted into town and turned around on a flat parking lot and got home. By the house, i turned into the hill where I parked. Daughter never even realized that I had lost brakes until I told her. ..

You might try this unapproved braking assist AKA a scrape bar, as shown in this 83?
As shown in use reply #30.
The wrecking yards used to come to get your car for free. And sometimes even give you a few bucks.
Perhaps they would have. For whatever reason, we decided to drive it.
Scrap prices are up like everything else.
PullaPart advertises 250 bucks if the car is pretty much intact.
Only reason I knew is that a friend did it many years ago. Then later I saw some ads in the local rag... $25 and we come get it free.
A couple years ago I was driving my son’s pickup and pulling a trailer.
I tapped the brakes and they were gone. (Brake line blew out)
I drove a further ten-fifteen miles before I pulled over.
I’ve never had a complete brake failure without warning, and don’t want to. I did drive a 1969 VW van for quite a while in which the brakes took a couple of quick pumps before they’d work, though. Finally got around to fixing them. That van had drum brakes all around, and they would fade really badly if you got them too hot.
These days, a set of brakes lasts me a long time. I don’t use them if I don’t have to, but I definitely want them then.
I suppose one could install run flat tires.
In my case they worked fine until I hit the pedal and it went to the floor.
