I bought new a 2006 F150 and noticed the wobble the first time I drove it in the mountains and braking down steep grades. I thought maybe warped rotors but had no issues on level highways at higher speeds when braking, occurs only braking on steep grades. Today west of Denver on I70 the issue was severe enough I have concern. It only occurs while braking unlike other reports it does not shake from bumps in the road.
