Hey Scotty, 2009 Ford crown Vic. I just changed the pads and rotors and when I make a sharp left turn there's a faint grinding noise coming from the front right wheel. Also is it normal for new brakes and rotors to squeal loudly? I have top notch pads and rotors too

no, make sure you didn't bend the backing dust shield, it will rub on turns if bent.

I think that might be the cause, I took It to a shop and I just so happened to make that noise right after? Can they be held liable for this? Im positive It didn't make that noise before

And is it an expensive cost to fix the backing dust shield along with labor?
