Recently I replaced my rear rotors and brakes. Someone notice my two rear tires are wobbly. I took a gander and to my surprise I was scared to death at the condition of the wobble. What could I have done to cause this wobbly on both rear wheels? What should I look for to resolve this?

Car : 2007 Acura TSX

I'd guess the new rotors are sitting flush on the backing plates, or the wheels aren't mounted flush to the rotors. You'll need to takes the tires/wheels off and check both. There must be something (rust probably) trapped between the wheels and the rotors or the rotors and the backing plates.

Simba91102, you were right about the rust.

In between the wheel bearing and the rotor was rust. It was useful to remove the rust with a wire brush. The little differences in irregularity was enough to make the wheel wobble. I have not necessarily had to focus on this before because the wheel usually tightens itself down onto the wheel bearing once the lug nuts are installed. There are two set screws for each rotor. This car was missing 1 on each rotor. This made the rotor not sit flush against the wheel bearing. I had to acquire two new set screws for each rotor to keep the rotor flush against the wheel bearing.



No more wobbly and I hope this helps.
