Check the hard lines for leaks, especially if its a rust belt car. Check the bulb for the brake idiot light to make sure it isn't burned out and unable to tell you something.
Not an MB, but my mom had the hard brake lines on her car rust away and give out one summer. There was a loss of a squirt of brake fluid at every stop, but no loss while parked, so it took us a while to figure out what had happened. Sensor must have failed too (or my mom ignored the brake idiot light until the bulb burnt out) because the idiot light wasn't going on either.
