Truck Wobbles When Braking?

I know y'all are gonna say warped rotors, but the strange thing is i dont feel any pulse in the brake pedal. I have a 1992 f150 4.9L engine 5spd manual trans. when I brake at low speed (25mph or less) I dont feel it. when I brake from 25MPH or higher, the truck bounces like it has a warped rotor, the steering wheel shimmys a tiny bit but the brake pedal does not move at all. ball joints and tie rod ends are only a couple years old. I dont feel any vibration when cruising, only braking. whats my issue here?Truck Wobbles When Braking?
I would still say Rotors even if you don't feel it in the pedal.Truck Wobbles When Braking?
Bent rim. You can prove it moving the fronts to the rear. The little cars are the worse. Evaluate if you hit a curb or parking lot obstacle head on.
