Looks like some in the industry are ready to have another go at brake-by-wire. Let's hope it is not another repeat of the 2005 Mercedes-Benz Sensotronic Brake Control (SBC) saga.
A brake calliper is a harsh environment for any electrical device. Lots of heat, vibration, and exposure to water, mud, dust, etc. It will be interesting to see what the as constructed components looks like.

... Benefits of EMB are said to include improvements to anti-lock braking (ABS) function with the pedal “buzz” a driver feels when the system engages disappearing, faster brake application, better managed front-to-rear weight transfer under brakes, brake ‘feel’ options, potential manufacturing cost reductions, fuel consumption gains (due to less pad drag), and longer component life...
AN’s report says the incoming systems replace hydraulic callipers with electric ones that use motors to move the brake pads, rendering master cylinders, vacuum boosters and hydraulic lines redundant.
“The brake pedal is connected to an electric device that measures inputs such as the speed and force the driver uses when pressing the pedal.
“A pedal simulator observes driver intent though pedal travel and force and translates it into a signal that is processed through a central computer,” said ZF director of engineering Diego Cusi.
“That signal is now going to be issued out to the four corners.”
Tyre grip on the road creates another set of signals allowing the computer to apply different braking pressures to each wheel based on road conditions.
“The signal (from each wheel) is going to be interpreted, and then it is going to command the motor to deliver a certain force,” Mr Cusi explained.
