Yes, this sounds like a case of warped front brake rotors. So the fix is pretty easy, re-machine your front rotors on a brake lathe or if they are too thin to re-machine, replace them. Of course, replace your pads if they are getting thin as well. I use the metal pad backing material as a guide, so whenever the pad friction material is as thin or thinner than the meal backing plate, I install new pads. I do this for several reasons, when the pads get this thin, they tend to get very hot and warp the rotors. Also when they get this thin, the pads can/will crack and start to beak away in chunks, which gets dangerous very quickly. I have seen 1/2 a pad just fall away after it cracked and on a Chevy truck with stuff in the bed that adds extra weight, this makes for unsure and risky stopping ability.

Yes. I'd say that the brake rotors are warped and there are loose front end parts causing the shake.
This could be very dangerous, especially if a worn out front end or steering part breaks causing the vehicle to veer absolutely out of control and maybe with no ability to stop. At the very least you need a front brake job including machining or replacing the rotors.
Get this vehicle ASAP to a GM specialist or an alignment shop and get it fixed.
