Hi all - I have about 190 miles on my new Entourage SE and I noticed that when braking there is a vibration that is pretty noticeable. I looked at the rotors last night in my garage and there are 4 or 5 score marks on each surface of the front rotors. There are none on the back rotors. There is no way that could be normal is there? Is that a symptom or the cause of the vibration? If any of you have any thoughts, let me know.

Dear mic,

Scoring at 190 miles on your Entourage? No, **** no. Have you been driving in a sandy or gravel area? I have 44,000 miles on rotors on a Tiburon, and they are still quite smooth. No vibration, no scoring, no irregular wear despite hard braking.

Your vehicle has to be under warranty. Get the dealer to check the runout on these rotors. While a rotor is a wear component in the brakes, these appear to be defective from the factory.

Just a quick update on this situation. The dealer had the van for a day and here is what they found. They test drove and felt the same vibration. The first remedy was to machine the rotors and then retest. Vibration still there. Then they replaced the rotors with new ones and then retested. That did it. When I asked the service manager what was the cause, he said that they could not be entirely sure but they thought that the original rotors were defective. I have had it back for a week and the braking is sweet! No vibration to be found. :460:

I've seen this a few times on new Sonata's. You get a real bad vibration in the steering wheel when you brake at any speed over approx. 30mph. The rotors are typically warped from the factory. Taking a few thousandth's off the rotors has always fixed the vibration.

my wifes 01 santa fe has had the rotors turned numorous times and even replaced and still get vibrations after 3 or 4 months.

I've got a similar issue with my Entourage.

There is a grinding when I slow to a stop. It's from like 5mph to fully stopped. I pulled the wheels and checked the brake pads and rotors, no scoring to be found, and the pads are at least 50%.

I've got 25k miles on the van, and I love it to pieces, but this is really worrying me. I've got an appointment at the dealer bright and early tomorrow to find the cause, and will update this post when they tell me what's going on.
