Update:
I rotated the tires today,poped off rear brakes and noticed they had shims and were already chamber cut(no pic I forgot).I noticed the front are not.
I dont know if the dealer did it when they replaced them or the rears come that way?.
My brother and I beleve they are factory cut.(no pic I forgot)
He said if they were cut by the dealer they wouldnt be that perfect.(we also looked at the cut on a new set off pads for a dodge truck)

Anyway left the front alone because noise is clearly in the back.
Used disk brake lube under and over the shims and on the side metal clips.

Result is that it seems to not make the noise but there is a little noise at the end of a hard brake(could be suspention noise its below freezing here?)

I will see how it is over the week but the long ratcheting groan seems to be gone.I think im getting very sensitive to noises.
Could it be so simple a little lube did the trick .

We also tryed to isolate the ebrake cable/spring at rotor(pic below) if you wiggle it it makes a simular sound that im getting.It didnt make a difference though.
