Sometimes it balances out a bit at higher speeds. You should probably have the rotors checked for runout and thickness variation. Some rotors distort under heat (highway braking) and may test OK in the drive but bad on the road. It's possible that it's a slight wheel balance or other similar problem. When you step on the brake it tries to stop the out of balance condition (by nature of the design of disk brakes) and you can get vibration feeding back. More likely it is the brakes. Bob
