Breaks Failed on 2003 E320
There was no resistance in the break pedal, opened the hood to find break fluid reservoir empty. No idea how that could have happened. I'll post technicalities when I hear more from the service department at the dealership. I am thankful not to have been in an accident today.

Good to hear that you are ok and didn't get in accident. Would have been scary if you were on a highway. Did you have all the recall and tsb's applied to the SBC prior to this failure?
I've seen a couple of older threads about SBC being the culprit in breaks failures. Seems like you are thinking I've had a similar issue. I'll surely let everyone know.
Being on the highway, in dense traffic, would be bad. But it happened in a residential neighborhood, I always see kids on bikes here. This perspective freaks me out. I think I'll drive the car again, might keep it for a couple more years. Not sure I trust the brand anymore.
I wonder is the dealer screwed up and the results are just now appearing.
I am not a professional, though. All I know- I didn't hit any objects, nor had done extreme driving. Maybe you are right- then I'm going to rip them a new one.

Does this mean the E-class becomes hazardous after 10 years of use
Just in case, I asked the service guy to give me all failed parts.
I note the Maybach and SLR still use this excellent anchor system.

If you were paying (buying) the replacement parts then the removed ones would be yours.
Just a guess.
BTW John... my '07 E 550 is a joy to own, and problem free! 3,000 miles on the odometer.

"To further support you, Mercedes-Benz will extend the warranty on the hydraulic pump within the SBC/electro-hydraulic brake system to 10 years with the unlimited kilometres from the vehicle start date"
"This extended warranty does not cover any other SBC/electro-hydraulic brake system component and standard warranty terms......"
So if the mechanic is telling you that it is covered under the 10 year warranty than it is most likely that he means the sbc hydraulic pump failed since if it is not the pump it would not be covered under warranty.
Mechanic probably said controller to deflect attention from the pump. But the 10 year warranty clearly states that other parts are not covered and only the pump is.

I cannot see how it could have had a slow leak, this should have been seen by a warning light for low brake fluid. Must have pumped the fluid out along with the failure?
Is there any possibility that the rear brakes were fixed with incorrect parts, making the brake cylinders come too far out and leak?

The leak must have been elsewhere. Since I assume you did not get any low brake oil warning before the big bang, the brake oil must have disappeared from the broken SBC pump, I wonder if that is possible?
PS. did you get some detailled info from konigstiger, could you let me know the document numbers (PM if you don't want to put them here), I'd like to learn what I should watch after on my W211.
