A shake only under braking is not balance
Vibrations get blamed on balance more than anything else, and many of them are something different. The quickest way to sort them is to notice exactly when the shake happens.
Only when you brake. A shake or pulse that appears when the brakes are applied, felt in the steering wheel or the pedal, and disappears when you let off, is almost always the brakes. Rotors that are no longer true produce it. Balancing the tires will not touch it.
At a particular speed, braking or not. A shake that builds in a speed band, often on the highway, and fades above or below it, is the classic sign of imbalance.
At every speed, getting worse as you go faster. That points more toward a tire or wheel that is out of round, or a worn part, than toward balance.
When accelerating. A shake that appears under power and goes away when coasting points to the driveline rather than the wheels.
Why the distinction saves money
Each of those has a different fix, and only one of them is a balance. A clear description when you book means the right work is done first, rather than a balance followed by a second visit for the real cause.
Note where you feel it too. In the steering wheel usually means the front; in the seat or floor usually means the rear.

A shake under braking is brake repair, and a pull rather than a shake is car and light truck alignment, both here. Every new fitting is balanced as part of the job. The national tire and wheel balancing page covers the other occasions worth asking for it.
