About a year ago I replaced the front rotors and pads on my wife's SUV. When I test drove it afterwards I noticed a slight wobble. I realized I should have had the new rotors turned as it was obvious they were warped out of the box. But, working 60-80 hours a week, I let it slip by.

Well, the wobble got progressively worse and finally today when I got home I jacked it up and pulled the rotors. I took to a local auto parts store to have them turned. Unfortunately, the tech at the auto parts store told me that both were too warped to mill. They would have hod to make 2 or 3 passes on the lathe to get rid of the warp. But, then they would be too thin.

Well, I knew they were slightly warped a year ago and I didn't take of them then. So what the hell, I have them pull a new set out of stock. (I bought old pair at a different store, otherwise I would have returned them under warranty.) Before I pay for them, I measured them with a pair of calipers. Sure enough, these are warped as well.

Long story short, the new rotors were warped so I had the store cut them. They also discounted them 25%. Ended up spending $140 for rotors and pads.

What ever happened to Quality Control. I guess he's with CROS.

Order brembo, wilwood, or bear brakes. They'll be flat.

I should have known the other ones were warped by the linear sanding marks. The two I bought today had the same marks which is why I had them put the rotors on the lathe, at not cost to me, before I paid for them.

The OE’s aren’t getting square rotors either… my wife’s Honda Accord has had them replaced twice with less than 50K. The 90’s and on GM stuff might as well been oil filters… Not sure who’s the supplier(s), but they suk.

Craptacular counterfeit parts, probably from China.

It's all about the manufacturing process. It seems rotor manufacturers are not truing the rotors on lathes anymore. By the looks of the tooling marks on the rotor faces the are either being belt sanded or abrasive wheel ground. Either way, they are not perfectly flat as they once were.

The Germans do make a great motor, transmission and suspension. But they have this eerie fascination with plastic. Look under the hood. Plastic everywhere. Expect a BMW water pump to fail somewhere between 60 & 80 thousand miles. The reason, the plastic impeller shears from the pump shaft. Also, around 80K expect the fabric on the roof struts and the headliner to start to come loose The radios are also known to be problematic.

Before you say it, I'm not someone that keeps a car 3-4 years. I like to drive them note free for a few years.

New rotors should always be turned. It's not about warpage it's about matching it up with the pad and thier positiong. If not done right the overheating can warp your pads..
