Weasel...or any others with input

I've started to pick up a shimmy while braking. It starts when brake is about 20% applied and stops as I get to about 50%. Started doing it only at high speed (70mph plus). I'm starting to notice at lower speeds. Indy says it's the rotors and to live with it till brakes need to be done (brakes and rotors have about 10-15 thousand miles on them). I feel (based on board search) that it may be bushings or some other front suspension parts. My X is 2001 4.4 sport with 103000 miles. To my knowledge no suspension parts have been replaced to date.

Thanks in advance for any input
