You guys catch Marcus's post...SBC is bye bye in 06
https://mbworld.org/forums/mercedes-tech-talk/128163-brake-wire-no-more.html
I never had any complaints.
Basically instead of having a brake pedal plunging a piston up through through a master cylinder and displacing hydraulic fluid through the various brake lines and ultimately compressing the pistons and pads against the surface of the rotors and clamping down and ultimately slowing the auto down.
The SBC system, uses the physical placment of the brake pedal with a position sensor. There is no mechanical linkage, other than pivot points, per se. Depending on the amount the pedal is depressed, speed of the vehicle and other algorithms. The different factors are 'chiseled' out by the car's onboard computer and will apply braking via electro-hydraulic pistons (electrically actuated) versus totally hydraulic, although MB supposedly has hydraulic backup.
Mercedes is supposed to have hydraulic back-up for this system.
My knowledge is still rudimentary on MB's specific systems, I'll post some more links later. I'm very skeptical of this kind of leap of technology in such a litigious country like ours by MB. Also, the posts I have read thus far on this very forum are very, very scary.
Here's an article about SBC failure. I'll post more stuff once I find some good posts for you guys.
Mr Bobcanada, you better care your very life could depend on it!

I'm in no way implying that failures do not occur. However, this could happen in any vehicle, with or without SBC. Out of millions of miles covered by all the cars with SBC, I would be willing to bet the amount of complete brake failures, statistically speaking, is on par with other systems. Thousands of recalls go unheard of all the time. However the press will target this one in particular because it is a premium brand and an exclusive technology.
If M-B was so worried about failures, it would have pulled the plug on the system a lot sooner than allowing 4 entire model years (5 in Europe), worth of production to pass by. It would have actually saved them a lot of money to have simply re-engineer the car with a conventional braking system than to go on with SBC. I'm willing to bet the real problem lies in the complexity of the system, not so much the chance of failure. Just because one part may fail, does not imply you will be left with no brakes. However, it would be much more time consuming and labor intensive to fix than a conventional system. This hits DaimlerChrysler where it hurts most, in the pocketbook.
By your logic, I should drive in fear that my brakes will fail at any moment. Thanks for your concern, but as long as the car is covered under warranty, I'll just enjoy it instead of assuming there is impending doom.
The Best of Mercedes & AMG

Just think about the added benefits like reduced maintenance, lower cost etc - it will happen rather soon.
I won't argue the fact that the concept is novel and in time may come to pass as commonplace. SBC has been fielded too early, in my opinion. From what I have read thus far, this is gonna bite MB hard in the wallet and rightfully so.

My cousing however had complete failure in his 04 E55, he said it wasn't too fun.

Right, StapleGun?
Right, StapleGun?
Anyways, if you think I live my life in fear you're sadly mistaken...sad to say you don't even know me. I can't believe that I'm pointing something out to you, about the vehicle you drive and I'm getting unsolicited wise-a$$ remarks for it. It just shows your ignorance
I hope I'm wrong and maybe you're just being facetious. Complete brake failure IS NOT a serious concern to you in a friggin NEW car. That must be BC bud you're toking, becuase it ain't the run o' the mill Mexican schwag. I don't have a dog in this fight...and hey it's your substandard engineered car that MB decided to roll the dice on and hope you die instead of live to sue. I hope I don't have one of my 'friends' scooping your rotting remains into a bag someday and you when you wake up (hopefully not with flames underneath your feet thinking, "....damn, that schmuck staple was right). Lord forbid, it happens when someone you possibly love drives your precious car and it happens when they are behind the wheel. Judging from what I have read you're much too selfish and could really care less about that.
But hey what the hell do I know...
mrankovic....your response is duly noted and well, I'll leave it at that....pretty much the same applies

but that's progress, of a sort.

Nope, I don't know you. But you really seem to know a lot about me.
I'm selfish, daddy bought my car, and oh yes, I'm also immature.
You dont even know what I do for a living, nor how old I am, nor my education level. But hey, I'm the immature and "selfish" one and you figured me out anyway.
From someone who does not live their life in fear, they sure do want others to do so.
From your responses it sounds like you are offended that someone who would spend $90k on a car would rather enjoy it than worry incessantly about a brake failure which, whether you believe it or not, is not a common occurence.
I guess I'll just join all the other W211 E55 owners who will the perilous drive home this afternoon in our "substandard" $90k 500hp cars.

All I know, is that it has been two or three different members with a relatively new car (all of them E55's), experience these pretty serious problems. That is all I wanted to convey to you, not to instill fear, by any means.
I have, many years ago, and with a car as old as me....experience a complete brake failure and fortunately in that lil' Mini Cooper the only person I probably would have killed is myself. After pumping the brakes frantically I was able to build up the presssure enough to stop. I only blame myself for that though, a broke college kid which should have parked the car until I could afford a restore, but I was stupid. Every junction in that hydraulic system was rusty from previous years of neglect.
With a car with 300+ ponies - I figured you would like to keep it intact along with yourself that's all. So happy motoring no one's wishing you ill here in FL.
