Hmmm should my rotors look like this?

[Twoblindsheep]

alright so im not sure if this is the right place to complain but im doing this at this point

i recently bought a Brand New 2011 camaro 2SS/RS and it was a huge upgrade from my 2011 2LT/RS.
now im not very good with cars and dont always understand whats wrong with my car when its right infront of me.
during one of our "meet up" someone pointed out to me that i need to get my brakes replace or something because they look bad. at that time i had no idea what he was talking about since the brakes look fine.
After doing my research and have 4 other people that work with me telling me that it doesnt look right and that i should get it replaced it finally hit me that something is wrong.. from what i was told something is wrong with my pads and they are leaving groves on my rotor.
heres a picture of 1 of the rotors.. i have it on all 3.. only one looks good.



now i called the chevy dealer telling them the problem and that since this car is brand new with only 700 miles on the warranty should cover it.
their answer.... "oh its a brand new car you need to break them in"
<---- that was my face... my 2LT didnt have it... or the crazy rust thats going on...

so whats going on?

Surface rust on rotors is common on just about any car, unless the rotor is made from a material that doesn't rust.

However, the lines are your rotor might be concerning.. do you feel grooves in your rotor, or is it smooth?

[tomlink]

If you run your finger across is there a noticeable groove or just appearance?

[Twoblindsheep]

def not smooth... they are pretty deep grooves. like you can hear it when i run my finger nails on them.
thats what im worrying about

That's not right for a new car. They'll agree when they see it at the dealer in person. If they don't, take it to another dealer, IMHO.

Where did you find a new 2011, by the way?

Time for some attention from the dealer.

hahaha i had to drive 100 miles to get it.. i knew i wanted a upgrade but i didnt want a 12.. i got super lucky on this one.. the dealership had 3 and 2 were sold right away and this one was sitting on the lot since 3/25/11 and i took it on 6-/09/12!
i even got 0% for 72months!

If you don't mind me asking. How many miles were on the car? I can't believe ANY car can sit on a lot for 15 months! Poor little thing lol. Glad someone took her home.

Wow, that's nuts. Super low for how long it was there. Great find!

[babytiger]

Not to hijack but we bought our NEW '11 June 23rd. Hit the lot 3/11. Had 1800 miles on delivery, now has 2800.

[Angrybird 12]

Hmm looks like a demo model that was driven hard, did the dealer use it himself to drag race? If the brakes look that bad with only 700 miles I would also worry about the entire drivetrain. There has to be a reason a 2011 had not been sold for that length of time. I hope you got a hell of a deal on it you may want to look into an extended warranty too.

[JohnnyBfromPeoria]

Great score, TBS.

Anyway, brakes work by having a somewhat softer material on the brake pads than what the rotors are made from. The pads wear considerably faster than the rotors as a result. When rotors get scored, as it appears yours are, they sometimes require a "resurfacing," where a machine physically cuts away the high points of metal until the face, both front and back, are smooth again. Trouble is, that procedure can only be done until the minimum thickness of metal is left.

Let me make a comparison, fair or not, as to wear characteristics. I had a Scion xB that I bought new. Fear not, it's gone now, after 155,000 miles. I replaced the front brake pads twice in that time (three sets total, and the third was still plenty good when I sold it). I never turned the rotors. In fact, I consider turning the rotors as a last resort, unless the brake pedal is "surging" as I come to a stop. Too much material gets removed when they are turned and a lot of life gets shaved off.

It's relatively rare, what I'm seeing on yours. The disc brake pads ride so close to the rotor when you are not on the brakes that material of any size cannot get behind the pads to scratch or score the rotors like that. I've only seen that condition on brake rotors where the old pads had been left on a car far too long and they dug into the metal when they wore out.

So what's causing it? It could be that the calipers, which hold the pads, are not free in their mounting. They need to be able to move slightly so that the pads maintain a constant relationship to the rotor that may be less than perfectly flat. This condition could result after a car has sat for a long period of time. This is the most likely scenario my little mind can cook up.

Frankly, it almost (but not really) looks like someone removed the calipers, packed rocks in the brake pads and reinstalled them. 805 miles is WAY too soon for anything like that to happen.

oops looked up the info and i was actually wrong. the car was build on 3/25/2011 and delivered on 05/20/11. so it was about a year on the lot before i took it!
oh and the best part is that my trade in vaule was more than how much i bought my 2LT/RS for! not by much! but its still a win!
and when i left the place my 2LT/RS was sold and i got to see it drive off with the temp tag!


heres a picture of my 2LT/RS and my new 2SS/RS

yeah i was worried about that too.. but when i first got there the car looked good! nothing wrong with it beside the front plate bracket
and yes i actually got the extended warranty and wheel & tires added on for free.. liked i said.. i got an amazing deal on this car! but i do agree with you.. 700 miles and this is showing... something is wrong.

[intensifi]

It looks like it sat outside a lot during a winter (or two). I notice the deeper rust on the rotor near the wheel mount.

If it were me, I'd ask for new rotors. The pads should be inspected when this occurs. If they have any foreign objects or ridges, they should be swapped also.

I'm told the new rotors are better at repelling rust.

yeah... i rather not have the shave it down.. i want them to replace all 3 of them including the pads.. i mean thats not too much to ask for a brand new car that i just bought right? lol
but yeah.. i was just pissed that the dealership said i needed to break them in..

yeah thats what im trying to get at.. but it seems like the dealership doesnt want to replace them by sayin that i needed to break them in... yeah okay..
but we'll see.. i having another person at the shop to look at it on monday.. this better be fixed before my drive down to indiana for camaro5fest

[cactuseater]

Tell your dealer they can have them and put them on any other new car they'd like and break them in all they want. You need new rotors, new pads, and possibly new calipers. Had all of them replaced on my 2SS within a week of buying it. They turned the rotors twice, against my wishes, and it was still a problem. Now, it glides free and stops on a dime. That's what you paid for, make them do it RIGHT. I seriously cannot believe all the BS we put up with from Chevy dealers on these cars. It's sad. Thank your lucky stars is not a convertible...they are nightmares.

Op It's a matter of the rotors and being made out cheap cast iron GM puts on our cars. Heres more info

Has nothing to do with that, those brakes were obviously abused.

There is no 3 in brakes. They always have to be replaced in pairs. You need 4.

I don't understand why it would be an issue to be on the lot for a winter.
Certainly you can drive the car in snow without eating rotors/pads.

BTW, I haven't had rotors cut in over 10 years. New rotors are not much more expensive than having them machined.

[JohnnyBfromPeoria]

Comrando, the pins that locate the calipers could have rusted in place while sitting, causing the brakes to constantly drag. Seen it happen.

You defenately need new pads and rotors. I had a '01 Monty that the pads went bad on, and that caused what you have. Grooves in your rotors. Make them replace them all the way around.

[Higgs Boson]

first,you may have to alert the selling dealer of the brake issue. brakes are a wear item and the is nothing to prove to a local dealer that you didnt drive that car hard for 100 miles.

a lot of cars celebrate their first birthdays on the new car lot. usually they are the ones with bird stained clear coat, low tires, and dead batteries, lol. the manufacturer will push inventory on dealers when there is too many in the pipeline. it sounds like this was a small dealer outside of a camaro market and no one in the country wanted one..... it happens. so it probably got 100 miles worth of test drives and I am sure they tested her real good like...lol.
