Yep that is why I stayed away from EBC pads you are not the first I have heard glaze them on break in procedure. They have prescribed mythology for doing it.
You are able to sand your rotors and I did it on factory pads as one of the many attempts to not come to a squealing (embarrassing) stop.
Just like cleaning a CD from center out. I am not sure if you can do anything to the pads or not I probably would pull them try a light "spot" sand, clean with brake cleaner and look, if it would appear to help I would have at it.
Make sure you spray rotors and pads spotless with air and then brake cleaner.
Do your self a favor and use Lyndalls next time
