Waynerm002 Posted December 5, 2004 Share Posted December 5, 2004 I noticed that my car has a slight vibration at around 60 - 80 MPH and when braking it is worse. I am thinking it is probably warped rotors. Is this a common thing? Firstly, no I did not overheat them, when I got the car and drove it home, I noticed it had that vibration but figured it was a balance issue. On my trip to work a couple of days after picking up the car I noticed the shudder while braking. I typically upgrade my brakes after the warranty runs out but I don't hink this should be happening with a brand new car. I saw in a couple of other post people mentioning this as well so I was wondering if this is a widespread problem or just isolated. I need to get it to the dealer to have it checked but have not had the time to do so. Pleae chime in if you have had this problem or know of anyone that may have had this. I have a 2.5i LTD wagon.

rkkwan Posted December 5, 2004 Share Posted December 5, 2004 If you have vibration when not braking, then it's not warped rotors. Sounds more like a wheel (or two) that are not balanced. Link to comment Share on other sites More sharing options...
kanoswrx Posted December 5, 2004 Share Posted December 5, 2004 I don't have any vibration when just driving, but one I heat up the brakes they feel wobbly when you get on them. It only takes 1-2 good 80-60 hard brakes to get them hot and to start feeling wobbly when braking on my car. It feels as if the wheels are unbalaned, but I know its not that because it drives perfectly smooth when not braking. I looked at my rotors just today after driving kind of hard and they looked smooth, no grooves. I don't know what it is either. Link to comment Share on other sites More sharing options...
SWortham Posted December 5, 2004 Share Posted December 5, 2004 Waynerm002, it could be brake rotor runout. I don't know how it would have happened on such a new car... maybe improperly torqued lug nuts? But the rotor can wobble side to side and cause symptoms like this. If the runout is severe enough, then I think the rotor may actually intermittently touch the pads causing some dragging even when you're not applying the brakes. If you think it's most likely the brakes, you could try to find a brake shop that will resurface the rotors while they are on the car. Doing it that way should solve any runout problems. And if it was caused by improper torquing then reseating the rotors could solve some of the problem, in which case you can even do that yourself if you have a torque wrench. Just loosen & re-torque the lugnuts on the wheels to spec. The sooner you do this the better, as the rotors will only begin to wear unevenly over time.

Waynerm002 Posted December 6, 2004 Author Share Posted December 6, 2004 Guys, thanks for the info. I am guessing that this should be covered by the B2B warranty so I am going setup an appointment at the dealer to have it looked at. Link to comment Share on other sites More sharing options...
