Okay, when Im going down the road I can hear this humming vibration. When I start to brake it gets a little louder and it starts to pop a little bit too. When I rest my foot on the heel pad I can feel it vibrating and stuff. Any ideas?

 

it could possibly be a wheel bearing. jack up the front end and support it on jack stands. spin the front tires by hand. if you hear something that sounds like a roller skate, your wheel bearing could have gone bad, and would cause a dull roar while driving. couldn't hurt to check
