The e brake seems good,I beleve it should be tighter it goes down far to grab.
Im going to bring it in on tuesday.

There is a separate brake shoe assembly that grabs for parking. The rear rotors are like a hat and the inside of the hat is a mini-drum brake. When you press down on the parking brake the shoes are cammed out and make contact with the drum.

I was wondering if the parking brake is releasing fully. That's why I suggested to pull on the parking brake cable to make sure the cable isn't sticking in its conduit. The foot petal may come back up fully but the cable may not be completely releasing. I know for fact that there have been H3's in to get the parking brake cable replaced and that the 2007's have a new design. You never mentioned that the brakes are grabbing or pulsing when stopping nor did you mention any smell or unusually high rear temperatures. My interpretation (which I could be wrong) is that the sound is a nuisance sound.

is that the sound is a nuisance sound.

No its a grinding sound definatly not normal.
Parking brake seems fine not to tight(If it was it would have worn down by now)Also it grabs low,probobly needs tightened .
Last time I checked the temp of rotor at my brothers shop and they were normal.

I don't think the sound is normal either - I was trying to get at if there are other issues you can feel versus just hear. The fact that you mentioned that the parking brake grabs low is a sign to me that the parking brake cable is not moving freely in its guide (not releasing properly), the parking brake is not adjusted properly, or the parking brake shoes are worn. Did you try what I suggested - tugging hard on the parking brake cable underneath the driver's side. It will feel tight to start with. If you tug on it and it frees up, you have a parking brake cable problem.

Fourfourto, do you feel a slight sensation in the brake pedal JUST as you come to a complete stop and JUST as you are hearing that grind sound? When I would hear the grind in the rear right, I'd also feel 'something' in the brake pedal. Almost as if I could feel the 'grind' in the rear brake. Chevy High Performance thoughts sound right on, too. But, you and I had the same grind problem months back .. so I'm tending to think warped rotor. I'm anxious to hear what they find out for you.

Dam what a freekin day droped off 3 they didnt have anyone to come with me for a ride so I got a loaner(another story see below)
They call me at 3pm say it ready and nothing checked out bad after they pulled all 4 wheels. Said Normal for hard stops on the H3 ?,I flipped out a little on the phone said I will come down and bring you for a ride.
Anyway Im driving back there a little pissed and a lady making a left stoped short and a young girl stoped short behind her in a mdx suv,I didnt see the first car.
I slammed the brakes and the 2007 silverado loaner rent a car slams her in the back f*cked up the front of the truck and the back of her mdx.had to get police report ect.
Anyway I called hummer to see if I could pick it up late after 5 and head sevice guy said they cleaned rotor (= brake cleaner)and seem better.He said he leaves at 5pm.

By the time I got there everyone in service was gone .
On the way home it wasnt doing it but I didnt come to many hard/downhill stops.
I will see what happens over the next couple hundred/thousand miles.

Bad day

If the brakes start grinding again im going to open a can of whip ass and go off on them like a crazy man.


First accedent in 20 years at least it wasn't my H3

Going to have a couple beers and calm down

OMG! What an awful day! Well, at least you weren't injured in the accident! (BTW, did you buy that extra loaner insurance they offer? ) Secondly, they sprayed my rotors with something the first day of the ongoing 6 weeks (before my problem was resolved), and it didn't work .. so you better pull out that 'can of whip ass' you mentioned just to have it handy. They told me SO many times during the 6 week period that the grind sound was normal for all H3's. EVEN after going for test drives with me and HEARING it!!!! You know it's not .. just like I knew it wasn't .. so stand your ground. I did. I've sent you a PM, too .. look for it. Let us know what happens, ok? Hope you're okay after the accident .. no sore back, neck, etc.

I had the same problem, I was about to order new brakes, I took it to a local shop and they just apply a cleaner to the rotors and rotate the tires.. done deal this was done on Sunday and no noice until today.
