Apparently as all other complaints are similar with the brake light coming on and as I apply pressure to the brake to stop the scrubbing and scraping sound is unbearable, I've been told it's the brake booster is bad for Infiniti Qx56. Fix the problem if everyone is having the same issue, please before someone gets killed. Also there's an exhaust leak which you can tell by a flickering noise when you crank up and accelerate.
