Hi Scotty!! My 2010 Equinox makes weird noise only when applying brakes. Started after the dealer rotated the tires but they claim it wasn't something they did and want to charge me just to look at it.

It's not a squeal or scrape. Sounds like a rhythmic ratchet sound, like a card in a bicycle tire. "Rrrr rrrr rrrr rrrr rrrr rrrrrrrrrr"

Changes pitch with speed.
What IS this!!

Thank you so much!
