Noise from front passenger side when braking

New noise on my 2006 X3 with 51,000 miles. Sounds like something is ratling around in my glove compartment when braking but only when coming to a dead stop does thenoise appear. I checked inside glove comparment then checked the control arm bushings, the brake calibers, bearings, shaking the tire to see if is lose. Can't seem to dupilcate te noise with the vehicle on jack stands. Any suggestions. I'm new to Bimmerfest so hello to everyone.
