Rear Brake/Axle Groan...

[Crash ?]

Somehow I've managed to avoid ever reading this thread.. I didn't want to temp fate.. Would rather not know there is a problem that could happen.. Wouldn't worry and be listening to every little noise that way..

Anyroads.. I scanned through the entire thing quickly.. Saw stuff about replacing pads, resurfacing rotors, sanding stuff, etc... If this IS just noisey pads it may be as simple as modifying the pad just enough to change any harmonic resonance..

The brakes on my motorcycle are some noisy SOBs... They squeal, they groan, they cuss at me, etc... I found that if the leading and trailing edge of the pads are cut off at a 45 degree angle, noises all but go completely away..

Just something to think about...

Maybe that's why mine stopping groaning (except for once)?

Im going to rotate the tires next month and inspect the brakes myself,I will have it apart so I might as well shave the pads It couldnt hurt.
I might also add lube and add shims if needed.


hmmm :The once it did it could thet have been the antilocks?

I was the passenger on that drive, so I don't know if it was the same as before with the brake pedal feeling, too. It had sounded the same as all the other times, though. I cringed and said, "Ohhhhh no ...". It was a pretty steep grade, though, and a very fast stop. I made a hard stop yesterday which SHOULD have made the groan (if the groan was going to happen) .. but, it didn't. I've never hit the brakes hard enough (in my opinion) to make the antilocks engage. Is it a similar sound, in your opinion?

silence is nice

Kinda similar.Grrr grrr gr
But different Gaaar gaar gar
Next time it rains/snows or in dirt(or the dry road if your a little crazy )get up to about 25 to 30 MPH and slam the brakes and hold it (no pumping ),you will here/feel it
Make sure no ones behind you, or use a parking lot.

Its good to check out how the brakes stop during a panic stop.

Short version....Im fvked






I get a call from the customer service manager from Gm.She tells me she spoke to the field rep and was told the noise I hear is normal.
File closed His decision is final.

WTF

She would'nt listen to anything I said(she did listen but said I can only go by the field rep)

She told me all she can do is send me forms for the BBB or I could call the attorney general .
I said send them

WTF

Also I asked about a extended waranty. she said Gm does not extend warranty on brakes

I guess I will have to live with it for now and try to fix it myself in a few weeks or 850 more miles at tire rotation ,Hopefully the brake lube and pad shaving does the trick

Or sue GM and cost me more then putting in drilled/sloted rotors with ceramic pads.

Had to vent ,Can you here the wife venting in the background,I think shes gonna go to hummer and shoot the fvcks

You've got to be joking?!?!?!?!?!?! She offered to send you BBB and/or forms for the Attorney General?!?!? Your groan is so loud, too, from what I heard on your sound link! My GM Customer Service Rep told me, too, that whatever the GM/Hummer field rep comes back with, is what he had to stand by... no matter what. I had quite a few problems other than the brake groan, so maybe that's why I got something from them. Brake groan, cylinder head, stabil-itrak, hood re-paint (twice), peeling A-pillar mouldings, now waiting on 2nd pair of mouldings, etc., etc. I had been without the H3 for long periods at a time.

I'd be very upset, fourfourto. Can you ask for the next person above your GM Customer Service rep? Was she the first person you spoke to, or the second? I had to go to the second person .. the first could only do so much ..like check with the Service Manager.

Does yours still sound as bad as it did in the link you had posted???? How can they call that normal????
