Hey daddio, for the record, my apologies if I caused any offense. I'm not trying to step on any toes. As previously stated, MB isn't "MAKING" you do anything. Replacing brake pads on an SBC equipped vehicle isn't the same job as on a non-SBC system. If recent history is any indication, SBC is here to stay. I'm sure other manufacturers will develop similar systems in the near future. As joe p says, the system can be de-activated with the properly updated SDS. Once the system is de-activated, replacing the brake pads is an easy DIY job. Hats off to vapors2K. One of the things that can activate the "Pre-Drive Check" is opening the drivers' door.
