Sounds to me like a wheel bearing or brake rotor warped, which is causing the pads to contact it when driving, but when stopping to make a vibrating noise as the pads try to stop an out-of-round rotor.

im having the same problem with my tundra... im starting to think, since i drive on gravel a lot lately, it could be my rotor...Or a rock got into my brake pad. etc just have the tire taken off and look at the brake components.

I’m having that same problem with my 2008 Chevy Impala. I could be stopped at a red light and you can just feel the vibration. I got all four brakes pads and rotors replaced and still the same noise/vibration

I have an 07 impala and its also making a rumbling noise from the rear while driving. It has new tires but also the brakes are grabbing and acting erratically.
