I'm new to this forum but thought I would try to get som opinions. Bought a leftover 2016 F350 SRW 6.7. I only have 3600 miles on it. The brake dust has gotten so bad that it is actually staining the wheels. I wash it off as often as I can. Went to Ford this morning to see about warranty. They say they'll get back to me Monday when Svc Mgr is in. What are my chances here?
