Dealer pads I here are big bucks,I beleve there are aftermarket pads that come already chamferd (shaved/beveled)

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.

Could it really be that your lube took care of your ongoing problem. You have to wonder why the dealer couldn't have done that?! Your dealer must have chamfered your rear pads the first time you took it in with the problem. The dealer who did that to mine (which I think fixed my problem) told me he did it (chamfer) because it would help keep the groan/grind away since I brake so much on windy, hilly roads. I don't think he would have explained it to me if my pads were already cut that way.

Anyways ... fourfourto, for getting to the bottom of your problem and fixing it. I hope you've heard your final groan/grind. If possible, try not to make aggressive stops .. ease into it as best you can. Good luck! Keep us updated if the groan starts up again.

Just took a ride up to blockbuster and no noise. silence is nice
Either the 3 is messin with me or it solved it ...for now.
I do here a faint "Ill be back"

The real test is if my wife hears it during the week.

F5/ parts guy
Anyone know if the rear pads are cut,they really looked factory cut I dont think I could have had them that even if I tried.
They might be factory replacement,that would explain why the fronts are not done.

LOL .. I know EXACTLY what you mean! I was SURE that I would hear the groan at the next stop! I'd cringe as I rolled to a stop and waited for the sound. I'm only now beginning to accept in my mind that it may be gone. I DID hear it once, but I wasn't driving it .. I was the passenger. No one drives it as well as I do.

Update:

After 3,500 mile round trip to FLA there is still no brake noise .

I guess the brake lube did the trick

Dealer had it in at least 4 times and couldnt figure it out

Less then 1/2 hour on the lift with my brother and I and the noise is gone.

That is GREAT news! Did you only lube the brakes? Did you chamfer new pads, or did you leave the old pads in? Isn't that amazing ... all of that grief and the dealer couldn't find it? I'm glad you're groan-free now! ()
