anyone see scoring occurring on their front rotors?

i have 600kms on my IRL

 

[JPK]

Yes. That's common in RL's. Someone said there is a TSB out on that.

Don't let the dealer tell you that it's OK because they all do that.

I need to take mine in for that as well.

 

[goofyguy]

gettin new rotors here this summer. they get to pick up the tab for that.

 

[my_bd]

how can you 'plan' to get new rotors in the summer?
and on their tab nonetheless?

 

[new2boost]

If there is a TSB on this can someone please post the number.

 

[kazkillinger]

what exactly are the signs of of this??? cause sometimes i hear grinding when i brake and the steering wheel sakes.......

I just noticed my steering wheel shaking the other day when I was braking. I guess I'll have to add it to the "ASK THE DEALER" list for this friday.

I've got some nice groves in my fronts as well. On my list of things to get looked at next oil change. I have never seen rotors get this bad so quick. Is this something that I can get fixed under warrenty. I mean 7000 miles on the brakes is ridiculous. I'll have to take pics.

I don't see "plan".

Hey I've noticed sometimes after hard braking my back left seems to make this weird noise. Its pretty loud and it gets faster as the car goes. but if I get out and kick the back driver side tire a few times it goes away. Could this be the rotors TSB you guys are talking about.

 

[Vita]

i never heard of a TSB for them, but it's been acknowledged as a common problem. GM cheap steel for the rotors. they resurfaced mine under warranty, and said to let them know if it's still a problem. nothing wrong with brakes according to them...

i'll just end up buying upgraded rotors when they're on their last limb if warranty won't cover

 

[SoCo Lime]

my rorors were shot within a few thousand miles and i was like WTF im not even braking hard

If you look at the rotors off the car, they are very poorly ventilated. Every other slot down the center is solid, perhaps to increase mass. I'm not sure. Also I've heard theories that the chrome finish on the wheels prevents them from absorbing as much heat off the rotors than a non chrome finish would. Eventually I'm planning on running ductwork from the openings on the front fascia to help with cooling. If I ever get time to design it so it looks nice.

Ummm, the wheels are aluminum and polished. Not chrome.

 

[Sp00ner]

and aluminum isn't exactly known for it's heat resistant properties...

 

[yrethguad]

I don't see "plan".

That's what I thought.

 

[yrethguad]

screw your Kia...

 

[dipolley]

Just an FYI. I am takeing mine in today for this problem. My cordaroy pants are smoother than these rotors. Let you all Know what I find out.

 

[WopOnTour]

Yes. That's common in RL's. Someone said there is a TSB out on that.

AFAIK there is no bulletin addressing premature rotor wear, and I doubt there will ever be unless a serious metalurgy issue is identified. (I dont see that)
GM regards brake wear as "normal wear and tear" and are often reluctant to address "friction surface issues" under warranty. Used to see similar early wear in the Firebirds and Camaros and it was "Dont drive so fast and brake so late and hard"

So basically we all need new rotors? Looks like I'll be getting the sets off of zfactor then.
