You're going to have to add a lot more detail or observations. When did this start? Where do you feel it; in the seat? Steering wheel? Entire car? Do you feel it at specific speeds? Only when accelerating? Has any professional inspected the steering, suspension, and tires?

If you don't feel anything in the steering wheel at lower speeds, we can likely rule out a broken tire belt. Another test for that is to observe a slowly oscillating steering wheel at real low speeds, as in when driving through a parking lot.

To only occur at higher speeds, and not under the load of acceleration, it's almost always due to a tire balance problem. I'd start by having them balanced. You can also switch them from front-to-rear and see if the feel of the vibration changes.

There are problems that can be caused by not following proper procedures during a brake job, but the results of that should be evident at lower speeds too. We'll discuss that if the diagnosis points that way. The clues there are you should also feel that shimmy at real low speeds, and, if you jack up the front of the car, support it solidly on jack stands, then run it in gear, you might see one of the wheels wobbling sideways a little. It doesn't take much wobble to be felt in the steering wheel.
