I wonder what sensors they use? Brake hydraulic fluid pressure? Pad position sensors? Pad-to-disk force sensors? Along with wheel rpm sensors of course. Fun to speculate.
I wouldn’t guess a brake sensor failure would lead to a no-brakes-at-all symptom. But I wouldn’t guess that a simple airspeed sensor failure could cause a commercial jetliner crash either.
George, meet Wiki:
Sensotronic Brake Control - Wikipedia
That Wiki entry is well written.
Especially pertinent is the section titled “Problems”. To quote…
“ In May 2004, Mercedes recalled 680,000 vehicles equipped with the system; in March 2005 a total of 1.3 million vehicles were recalled. In 2006 high-volume models such as the E-class returned to conventional hydraulic brake systems. Low-volume luxury models such as the SL, the Maybach and the SLR continued to use SBC due to the prohibitive cost of redesign.
In a letter - only to US customers - dated August 2018 a warranty addendum was sent extending coverage for 25 years and unlimited miles on the following SBC components.
Out of warranty repairs of these items can be reimbursed by MB if proper documentation is provided.”
