Car Shaking Problems
Brake Pads and Rotors
Hyundai Elantra

What could the problem be if a 2000 Hyundai Elantra shakes when applying the brakes when going over 55 miles per hour?

Perhaps it has to do with the antilock brakes?

By the way...Any electric problems?

IT IS NOT antilock brakes, on mine it was that I needed brakes.I replaced the pads and had the rotors cut. No problem since then.

Now the steering wheel shakes between 65 and 75mph but I don't think that's the brakes.


AnswerWhen your braking at higher speeds there is much more heat generated within the brake system. It can get so hot that brake rotors will temporarily warp until cooled, giving you the vibration while braking. I strongly recommend replacing the rotors, not machining them. IF you make them thinner, the are even less likely to be able to dissapate heat and you will be back in the same boat all over again. Put new pads on at the same time for 2 reasons. One the old ones will not mate up accuratly to the new rotors and give less surface area for stopping causing a longer braking distance. Second, the beating the pads that from the pulsation that you are putting them through will comprimise their integrity. In Dave's case the higher speed vibration is likely attributed to a wheel balance problem.

Get your brakes checked. It can be something simple, or it can mean impending doom.

According to Edmunds ( the 2004 Hyundai Elantra can tow 3,086 pounds with trailer brakes, and 1,000 without. The article does not specify which powertrain is equipped. The third generation of Hyundai Elantra design spans from 2001 to 2006, and may likely have similar mechanical qualities. For further information, try contacting Hyundai directly at 1-800-633-5151.
