Why does truck sound like I have mud tires on it while breaking?

I have a 2002 Dodge Durango and when I press the breaks it sounds like I have mud tires or big tires on. It also kinda sounds like if down shifting. I took it to two shops, one was a tranny place and it's not the transmission. She is also making a whining sound at 30mph.
