I don't think the tires need balancing or the wheels aligned. What other parts could cause a shimmy only while braking? "I don't claim to know everything... Just more than you."

A tiny bit of dirt could throw the disc out of true.

My dealer changed the pads and rotors when I bought the car. 7000 miles later they started warping. I changed the rotors myself with new ones, and 7000 miles later they started warping...I see a Ford trend here... Ryan M.
