I have this exact setup.
I assume you mean that only a portion of the pad is contacting the rotor. Note that much of the rotor is not touched even when the pad is at full contact.
Anyway, mine started at the outside edge, and slowly came into contact across the entire pad surface. I read two sets of instructions that said either 100 or 200 miles, but things still seemed not quite there. Everything is fine now, though.
What kind of miles are you putting on? Highway or city?
