That's a very interesting article.  That would 
explain why my rotors worked great for 35k miles 
then started getting worse and now are getting 
worse and worse faster. A death spiral!  Or does 
it?  Did I not get them broken in properly and it 
took 35k miles for it to show up?  Seems like 
that would have shown up sooner.  I guess the 
other possibility is that I had an "event" where 
I stopped the wheels with very hot brakes and the 
pads "imprinted" on that spot and started the death spiral.
