I originally suspected CA bolts or shock mounts but all were tight.
Then I tapped the rear calipers and they click/rattle.

Verified by going over the bumps while applying brakes and it doesn't make the noise then.
We had this same issue which lead to the rear brakes locking up.. the left rear pad was left looking like a leaf while the rotor was pitted and eaten up as well.. I would have someone remove the rotors and check the emergency brake and if there is any sort of build up inside the rotor (as our did) the e-brake would constantly make contact and simply wear out.

here's that post as relating to our issue and at first we thought it was an electrical issue.. But often one could dico the battery and clean the terminals.. Brake The Electrical Issue

Good points. Everything looked good when I just had the rotors off a week ago.
I just never thought the bracket and guide pins were a wear item

Update...

Pulled the calipers apart and filled the slide pin holes with caliper grease and cleaned up the anti rattle clips and noises are gone.

Thanks for that great advice

You're right though...too many electrical interventions going into these things.
Not like my old Dodge Ram Prospector. Those were the days....
