Two things came to mind when you mentioned the tires loosing air. This suggests to me that the tires are older and in need of repair. So, first off I might think that they have gotten low sometime recently and that there is a possibility of a balance weight having been knocked off a wheel. That would cause the vibration. Alignment could be another. Yet another cause could be that one of the tires is failing and has a weak cord.
Next thing you mentioned was the vib when braking and that will be associated with a slightly warped rotor on the brake system.
