In my car when I stop from any speed it pulls fairly hard towards the left. At low speeds, there is a slight pulsating feeling at speeds from say, 15 mph and below when I brake lightly. When braking hard, it knocks and then it goes away. I am thinking maybe the left front rotor is a bit warped but any ideas on this one?
Thanks much
Ben
