Brake Disc Pads Problems of Dodge Nitro

I have a 2008 Dodge Nitro 4x4 3. 7l . My rear break pads have worn about 1/8" into the rotor. I had gotten new tires for my vehicle not too long ago & ever since then I have been hearing what sounds like a clanking sound that seems to be coming from either the driver side rear or front tire area. It only makes this sound between speeds of 5mph to 30mph, then it seems to go away after doing 40+mph. My breaks don't squeal or make sounds when I push them. Only when I accelerate from a complete stop does this clanking sound occur. I have not inspected the rotor yet,but looks fine from what I can see. I know I'm gonna need new break pads soon but I have no clue what or where this sound is coming from.

Automatic 2 wheel drive emergency brake will not hold when applied. Took to Dodge dealership several times with no success or repair. Was told nothing they could do about it. Recall on 4 wheel drive only. Had new brakes- rotors- calibers and pads installed emergency brake still not working. This is a serious safety issue.
