Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).

the car has a pronounced "shimmy" when applying the brakes. Worse at higher rates of speed.

Warping of rotors...so the cars shudders as brakes are applied. Should not have this issues this early.
Brakes replace 10K miles ago, now starting to squeak when backing up and starting stopping (from a low speed).
Got this problem taken care of a few years ago by a local independent. The brakes would shake slightly but what I noticed first were the squeaky brakes in the cold mornings. Factory pads/rotors were installed and the shaking problem went away. The original rotors seemed to have been warped.
