Front brake rotors have warped from being hot. Have been turned once and replaced once. (owned by auburn university, fisheries dept. Auburn university, al 36849) consumer states he noticed the brakes would pump when making a stop, mechanic advised consumer that the metal alloy in the rotor might be the cause, the rotors were turned but problem came right back, and the next time they were replaced, also vehicle shimmers in the front end when consumer hits a small bump in the road, the entire fornt would vibrate violently, dealer replaced the front shocks which helped for awhile, later the steering box was replaced and that seemed to have helped the problem.
