Brake problems! on 2006 Pontiac G6

I have a 2006 Pontiac G6, When I drive long distances; sometimes short distances. My brakes get extremely tight. To stop, I dont even have to press the break. The tires shake as well. I just got a tire change and alignment. Any advice would be nice!

Could be a faulty brake master cylinder not returning brake fluid. Have it properly checked or it will boil the fluid and warp the brake rotors.
sounds like sticking break calipers too me
