Ran into another H3 with my problem yesterday ...

[fourfourto]

F5 Doesnt the e brake have a seperate pad (scrub brake).
My brother and I noticed it on my prevous brake inspection.

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.

[f5fstop]

got me; I forgot, still thinking old days. I'll do some checking tomorrow on brakes.

[fourfourto]

F5 we didnt remove the wheel but my brother said the placement of the cable on the backing plate it seams theres a scrub brake.
If you could confirm this that would be great.

I made an appointment for tuesday 9am,sevice manager said no problem replacing brakes and rotors in the back if its the same problem,He also said they wouldnt turn down the rotors a second time.
SM said if I will get a loaner if needed.
They treat me good over at ramp hummer they always give me a loaner

You HAVE been lucky in that regard, fourfourto. Your dealer seems to step up to the plate and always tells you they'll replace parts. I have to wonder if dealers here get 'points' for not replacing warranty parts.() It would be awesome to hear a Serv. Mgr. just come and say, "Yeah, we're gonna replace your rotors instead of turning them .. new pads and all, ESPECIALLY since you've been having nothing but problems with them." Uh-huh.

F5,

Any word about defects etc on the brakes???

RYD

[fourfourto]

The service guy did mention something about a notice about the brakes.He didnt show me anything .

They wrote this on work order.
C/S when braking hard there is a grinding noise.Verifed concern. Norn=mal condition for vehicle when braking hard.

I told them it does it on normal braking going down hill with stopping at the bottom without feathering of brake.It doesnt have to be a hard brake.

Ill wait till it gets worse and will go with them for a ride and say YEH ! thats Normal! Yeh Right !. and if I have trouble with them doing a repair I will insist on a hummer rep. I will give it a few weeks and see what happens.

Anyone with any info from gm for the H3 for brakes please list them. thanks in advance.

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.

[fourfourto]

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.

X2 thats they way it is now and was then.

Hopefully fixed by tommorow afternoon.

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

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.
