I replaced my brake pads today with my friend. After a bit of driving I heard a loud scraping sound coming from the left rear rotor. We had used an impact gun to get off the caliper bolts and one bolt on the right rear was seized but ironically it’s not making noise. I called my friend and he said it could be anything from contaminants on the brake pads, the rotors or the dust shield rubbing against each other etc. should I take my car in for a brake inspection?
