I've been a mobile detailer for 15 years today was first I ran into this. Customer of mine mentioned today that she took her car in to have brakes checked. She had some noise and thought they were worn. Brakes were fine and only thing mechanic could find was some of the tire dressing on the brakes. I apply dressing with a brush so at first was confused on how it would have got there. Sometimes though I spray in the fenderwells but not sure if that would do it. Sometimes I do spray the tires and can't remember if I did this last time. Curious if anyone has heard of dressing doing this. Dressing I use is a water based.
