1998 Dodge Dakota "Clunk"


My 4x4 truck has been making a ?clunk or clank? sound when I apply my brakes. It?s been doing that for a little over a year now. The sound happens 99% of the time I use them. I took it to a mechanic last year concerned it was my breaks. They said it was the steering column or rod hitting the adjoining (coupling or something) rod. That didn?t make sense to me so I put off the repair (plus I don?t trust those guys anymore). Does any one have any ideas and or does their analysis sound correct?
