I have a 2003 350z with 37000 miles on it. I brought my car out of storage last month and everything was going fine for the first few weeks. I could tell that my rotors were beginning to warp. But before I got a chance to replace them I experienced something that I can not figure out. I started driving and after about 3 blocks the car begins to lurch almost like I had a flat tire. I can tell that it was coming from the rear of the car. Since it was at night I was not able to inspect it until the next day. I took it out the next morning and after a few blocks I had the same problem. When I got out I could see a lot of brake dust on the driver side wheel. Does anybody have any ideas what this could be? Any help is appreciated.
