Default Vibration at Highway Speed

I'm experiencing a bad vibration at highway speeds. It is very evident when the brakes are initially applied at high speed (100+ km/h or 60+ mp/h), like a badly warped rotor, but goes away once the brake pressure increases.

I'm thinking it may be suspension or steering-related such as a ball joint or tie-rod because of how the vibration goes away once the brake pressure is applied. Has anyone else experienced this?

I have all original brakes which I will be replacing soon. The fronts I think are OK (just worn) but the back has a slightly warped rotor.

I think those still may be symptoms of warped rotors.

Thanks. I agree and plan to put new rotors and pads on in the next few days. If that doesn't fix it then on to the next possibility.

Replaced rotors and pads Friday but I haven't yet had a chance to take it on a good drive to determine if the vibration is gone. The old rotors were hell to get off due to corrosion on the inside catching on the wheel bearings. I basically had to hammer them off with a BFH. Bearing surfaces were cleaned thoroughly and new rotors and pads installed. Two 18mm bolts hold the caliper brackets on. The top one is difficult to remove and requires that the bracket for the brake hose be removed (13mm).
