Brake Chatter and Lifting???

I have a little problem with brake chatter at the end of a stop?  My brakes are good, plenty of pad and shoes on all, roters and drums are smooth and clean, no leaks nothing. Depending on the temp and humidity the brakes squeel or squeek at times.  But when I come to a stop the brakes chatter at the end at less than 3 miles per hour and the truck seems to lift just a little at the end and makes a funny noise like a click as it lifts.  Wonder what is causing it...Any thoughts?
 
Thanks

Did you look real carefully at the friction surfaces for cracks or just the thickness of the pads or shoes?
I've run into that problem, especially with rear brake shoes.

Not inspected that close.  Looked fine but did not see anything from the eye.  I could just change out the shoes. That's a cheap fix is it not?
