Rear Brakes making noise

Greetings,
I've got a 2001 Montana. I put new pads on the front about 2 weeks ago and every since then my back brakes have been making a noise. The noise ONLY happens when the van comes to a COMPLETE stop (noise only last about 1-2 seconds). It's not a grinding sound it's more of a clunking/binding sound (hard to explain the exact sound).

Any ideas? Could this have anything to do with changing my front brakes?
Any help would be greatly appreciated!

Thanks

Mine do the same thing. I have adjusted mine and they still do it.

My girlfriends van did the same, it is brake dust sticking between the shoe and drum. Nothing to worry about, just aggrivating. Clean them out with brake clean and it will go away, for a while.
