Almost crashed with a police car in front of me and was able to skid onto a side block. Once I got there I still didnt really understand what exactly was happening and again pressing the brakes absolutely nothing, no stopping power at all. I was lucky enough to be able to safely let the car roll to a stop; however if I would have driven a minute or so more I would have been at speeds of 70+ with failing brakes. MB roadside came and picked up the car and towed it over to the dealership and frankly I dont even want to get back into this thing. I don't want to have to worry everytime I get into this car about the brakes failing, which is unfortunately running through my head over and over. I've had the SBC brake recall performed not too long ago and thought there was some sort of backup system that would allow me to stop even if the electric one malfunctioned; however that did not activate at all. Has anyone had this partcular issue happen to them and any ideas of how I should approach my dealer. I really do not want to drive this car ever again

To begin brake job this week on my 2005 E500. Haven't heard the above on the many tutorials videos and such. I have been watching FCP Euro videos.

Is the recommendation legit? If so what is at issue?

There is also a complicated procedure to disable SBC using key clicks and HU buttons inside the car. It’s been about 10 years since I have had the E320 so I don’t remember the sequence.
Not disabling the SBC before brake work will result in damage or injury. The SBC sets the brakes when the car is unlocked or a door is opened to prevent roll away.
Pulling the fuse might work, and so might disconnecting the wiring harness at the control unit. But doing anything not approved could affect the function of the brakes and might turn out to be dangerous.
