Lately ive been hearing a scraping noise coming from the passenger side wheel well. So i took a look at the rotor to see if something was hanging on it causing the noise. And what do i see? A HUGE scrape along the edge of the rotor. Its about half an inch wide and goes the circumference of the rotor. What the hell happened? Is it possible to turn the rotor or is it considered warped? What can i do without having to buy another rotor right now. I'm about to go pull the caliper to see what's causing this.
