Hello everyone. I had extreme vibration when I hit the brakes recently and I decided to check out my rotors. The rears looked very worn and felt uneven when I dragged my finger across them, but the fronts are very smooth and look like they are fine (I'm at 55k with the original rotors). So I decided I would change the rear rotors and replace all four brake pads on my car, and also replace the steering stabilizer.

I ordered 2 Balo rotors for the rear and Akebono pads for all 4 wheels. I also ordered the stabilizer from joetlc. After replacing the rear pads and rotors, the steering stabilizer, and the front pads I would say the vibration decreased by about 80%, but there is still a vibration when I brake although it is much less. So I decided I would try to get the front rotors turned since they are more expensive to replace. When I took them to get turned, the guy told me that he couldn't turn them because they are too thin but he said at the same time that they appear in very good condition and do not need to be replaced. What he said really doesn't make sense but since whatever they have on record for minimum thickness for our rotors, it wouldn't let him turn them.

So now I am confused, they really do appear fine and I don't think they should be worn out by 55k miles but I am still getting vibration when I hit the brakes. Is there anything else that could be causing this besides a warped rotor? All my calipers and pistons appeared to be fine during the change.

Also, I am now hearing my brakes squeak as I am driving but it stops when I hit the brakes. This noise was not there before. I applied the brake grease on the back of the front pads, but the rears did not come with any grease. What could be the cause of this noise?

Sorry for the long post, just thought I'd share my situation in detail. Thanks in advance for any advice/input.
