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?

Update:

if it were a bent rim, wouldnt i feel it no matter what? and ive never hit a pothole hard enough to bend it, and the only time ive hit a curb is from taking turns too tight in parking lots, and i just go over the curb then!

    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.

    If not a warped brake rotor. i might examine for worn suspension aspects (tie rod end) and then examine the alignment. The shimmy which you're experiencing might maximum probable be led to by uneven tire placed on. The Explorer has constrained adjustment for caster, and no adjustment for camber with out the setting up of service bushings interior the top administration arms. this occasion might reason diagonal banding (uneven placed on around the exterior of the tire) a smart alignment technician can diagnose the problem with an inspection of the tires and suspension.

    I would still say Rotors even if you don't feel it in the pedal.
