Mercedes Anti Lock brakes

[MossHillHobbit]

I own a 2003 Mercedes C-class coupe, a little 230K. I want to change the front brake pads on it soon, but I don’t know how to turn the anti-lock brake system off (and then back on afterwards). It has the anti-lock/anti-spin ESP sytem. The ESP has an on/off button on the dash, but I don’t think that necessarily turns the ABS off. Aftermarket manuals don’t have specific information like that (none that I’ve ever heard of, anyway), and I don’t want to buy the manufacturer’s shop manual because sometimes they don’t have information like that, either: it’s in a shop bulletin or tech training class instead. Also, once I have the anti-lock system turned off, can I flush the brakes in the old way, by bleeding at the wheels, longest line first to shortest line last?
