Both the shimmy and squeal could be warped rotors.
I got my car in 12/06 and within a few months the brakes squealed.
Just like yours, moving very slowly with light braking.
The dealer machined the rotors. Problem fixed, for a while.
A year later I coated the pads with disc brake quiet.That worked for a few years.
The squeal came back and i started noticing a braking shimmy as well.
I replaced the rotors and front pads. I coated the new pads with disc
brake quiet and let them dry overnight.
In my case the new rotors fixed the braking shimmy and possibly the squeal as well.
My factory pads were in great shape. Did I need new pads? Maybe not, but i was sick of that squeal so I did the pads when i did the rotors.
Edit: Did you hit something to bend the wheel or just a defective wheel?
