NOT while braking NOT while braking NOT while braking

Can I make that clear please to the internet that cant answer this question

Why would a brake pedal vibrate when going over 60 mph. Whilst moving. Again NOT during braking, MOVING

Goes away below 60, doesnt occur till 60 , doesnt get any stronger or worse with more speed, just vibrates.

To me, it would indicate something about a disc rubbing on a pad, but there are no other problems or symptoms of anything. Nothing below 60 and nothing while braking at any other point, nothing visually wrong with discs or pads. I can't see why drum brakes would do it, but someone inform me if there is. Possible stuck pad that eventually starts vibrating against the disc?

Can this be fixed without having to get new components?
