I've been talking with experts about tires and balancing and "out of round" this past week. Some frustrations regarding my new Pirelli P7 "winter" all season tires from TireRack (for another thread someday, I decided to keep the OEM ecosavers and to put them back on for late spring, summer, and fall). Anyway, one of the most knowledgable experts said to me, you know you have not done anything to break-in your brakes and the discs are getting rusty. I replied, off course, I am an EV driver, and hardly ever use the brakes (with some satisfaction). What I did not get, is that apparently some break-in, is supposed to be good for the brake discs and brake pads. So, he encouraged me to use the brakes more, especially during these early miles. Interesting.
