Dealer joke!?/rough rear brake rotors?!?!

[Hum2]

Had my H2 in for numerous minor warranty issues...again...as usual...nothing new!

But...I had noticed that the rear brake rotors seemed a bit rough compared to the front rotors so I asked the dealer to check the brakes.

Their response "the rear brakes are rough due to off-roading" I was pretty ticked off with that statment. The service manager had nothing to add/justify that statement, so I will stop in and discuss this with the service/mechanic manager...and perhaps the owner after that.

Also, once under the truck, I checke the rotors in more detail...only the outside (toward the vehicle center) rear rotor is rough, not the inside. The front rotors are both smooth.

Sooo...what part of off-roading causes rough outside rotors? You got me!?!?

Any opinions here?

Hey Phil:

Definitely,....I think,....it's because you have off-roaded on only 1/4 of your outside drivers side front rotor!

the dealer is bull****ting you. gm has problems with bad casting of the rotors and they pit.mine are the same way on the inside surface they make no noise and don't pulsate and stop fine. so i won't bother filling out the six pages of documents so i can put new ones on under warranty.

[usetosellhummer]

go for the slotted aftermarket sma roters when yours are done. Could it be the dynamic perportioning?????on the rear

[Hum2]

Yeah, don't I know the dealer is full of it. They must really think I'm stupid, but in reality/in the long run, they are!

I don't quite understand them...if it is truly a warranty item...just fix the darn thing. They always act as if they are doing me some great favor.

Maybe they are losing money each and every time they have to do warranty work, and are under the gun to "not" perform any (or as little as possible) warranty work. Maybe that "please fill out the service survey with 100% satisfaction is really a plea for "please don't bring me any warranty work or it makes me look bad?!?!

Well....I had a chat with the mechanics supervisor/manager. What a waste of time. When trying to justify there stupid statement, they just stick their foot in deeper. No they don't pulse, no they don't grab, no they dont squeal...yet!

The thing that really gets me is the stupid statement that this was due to off-roading, and the fact that they gave no answer to my original question..they're pretty rough...is there any problem (less a damaged rotor)? After squirming around my questions for 10 minutes, he said they would pull them next time I'm in, to check them.

I physically went in last night to drop off some OMAHOG Event Flyers, and there sitting was a construction contractors trade in...60K, and dirt/mud all over the under carriage. Checked his brakes...all as smooth as glass. Hummm!

I will be pressing this issue....not only with regards to the brakes, but replacement rotors as well....not just a cheesy grind job! :-)

The quality of service is rearing it's ugly head! What is their problem/issue. Perhaps they're in an HMO where they are graded/paid on "not" providing service?!?!

I wonder what Hummer would say if you called them and told them that the dealer said that off-roading damaged the truck?

</div></BLOCKQUOTE>Well, with GM's financial situation it only stands to reason that warranty work would be scrutinized by GM much more closely and GM would put more pressure on dealers to not just err on the side of caution quite as much.

Ric, try to get a digital camera in there at the right angle to show the roughness and print and take the picture to the service manager. I do this every time I have an issue and make sure the picture captures exactly what I am talking about so that they cannot argue with it. There is no logic to "off roading" causing pitting or roughness to the rotors. You would have grooves dug into the face of the rotor all the way around if that was the case. The damage would be symmetrical around the face.

I also wouldn't settle for anything less than a replacement rotor as it sounds like a bad rotor and not environmental factors. Turning the rotor is not going to help as the pits will probably show up again after a while.

[Hum2]

Thanks guys!

I actually don't have any pitting, only a very grooved rotor (side towards the vehicle center), and only on the rear brakes. The fronts are OK as are the rear (side towards the wheels). The service manager stated something to the effect that none of what I said mattered as GM only warrants brakes for 12,000 miles anyway. ???

Seems like an excuse to me!

I am a machinist\engeneering maintenance tech for Anheuser-Busch of 14 years. I have 10 years at other places before that.
If I were inspecting this thing I would pull off the caliper and look for forigen materail that perhaps lodged there or evidence of said. And if this had been the case it could have dislodged long ago. And perhaps when the pads were made somthing hard could have got into the mold? some of the other problems listed in this post could have come from lack of lubricant on the pad retainer bolts \pins inside the seals, preventing the pads from floating free and self adjusting.
But the bad news is brakes are a wear item and getting them repaired under warranty is a tough go. You would have to convince them of the defective materials or workmanship (no lube om the pins). You have your work cut out for you.

Ric, I think what Don was really trying to say is that you are a bad off-road driver

Give Mike P. a call up north and see what he thinks about it. Might be worth the drive up there.

[Hum2]

Thanks all!

therock: Good advice...I had already pushed the service manager to pull the brakes next time I'm in and check them....something I think they should have done the first time. Anyway...my real issue with them was that when I asked them to check the brakes, their answer was "the rear brake rotor is rough due to off-roading" But they have no proof of that, nor did they answer my real question...are the brakes OK?

Klaus: Have a number for me to call?

PARAGON: Good idea on the pics....I'll see.
