It appears that removing the wheel and replacing it corrected the problem.
I noticed a small chunk o' concrete on the floor of my garage after I moved
the car. Don't know if it was the culprit for sure but the noise is gone.
I tested the brakes hard in a parking lot and they are working fine.

Thanks to all that replied.
