So, how do you know for sure that the pad is completely touching all of the rotor before doing the bedding runs? I'll be putting these on the existing rotors, which are already shiny/worn across their face. Does the 'brake in' red coating mark the rotors in some way? I suppose I could also just look for slight surface rust, but the BMW rotors don't rust anywhere near as much as other rotors I've had, making it hard to see.

Yes, you will notice a different color on the rotor... at first you will see a band on the outer part of the rotor which will get bigger towards the center of the rotor as miles go by and eventually will cover the whole surface of the pad against the rotor...
