Primarily the shaking is most noticeable when the front rotors are wrapped. The rears will make shaking as well but many times not as noticeable.
Sometimes the shaking/vibrations are hard to diagnose as they car lead you to the wrong item.
But if the rear brakes has not been changed in a while it will be a good idea to inspect them.
Also keep in mind that a tire issue like a flat spot or uneven wear can also make the vehicle shake when you hit the brake.
The best way to find out is the rotors are wrapped, is to do a runout test. In this test you will have to attached a gauge to the rotor and turn it. It will show if there is unevenness in the surface which might not be noticeable with a visual check. (see diagram below)
