well i dont know if this has been posted before but i just noticed this the other day......my passenger front rotor has a pretty little gutter a little further in than center.....i only have 8000 miles on the ****** and i have a gutter in my rotor... ....is this normal in the balts....it wasnt in my past 2 cars.....any ideas?...and any idea if the dealer will do my brakes for free because it is so soon

mine are grooved on the backside.... i think it is the rotors....

joes407

noticed some grooves on the front rotors here as well with 5000 miles. the bumper to bumper should cover rotors i would imagine. ive never seen a grooved rotor with the original pads unless they had rivets showing. maybe they are lead rotors <<< rofl.

It's iffy if they'll fix it, most of the time rotors are considered a wear and tear item, but if you've only had the car for 12 months or less you could probably get them to fix it if you yell loud enough.

ive only had it since valentines day of THIS YEAR.....that is less than 3 months....so im goin to the dealership.....

welcome to the "grooved rotor club" mine will be getting repaired the 2nd time this weekend

Skottish

did they do it for free by any chance?.....dont really have the spare $ for new rotors

Rotors on a base LS should last *at least* 75k miles, possible longer if you don't brake hard. I'm not sure about the SS/SC since they're different, but regular rotors should last a damn long time. On my last car, I drove over 80k miles while I owned it. Went through 4 sets of pads, 1 set of front rotors, and the rear drums and pads never needed to be replaced, only cleaned. The front rotors were replaced at about 110k on the odo.

In other words...the dearship better replace them for free if they're wearing abnormally.

Cobalt443

they do it for free as long as it's under warranty. this is a known problem. they will have my car the whole day tomorrow to figure out why it's coming back

im going in tommrorow for an oil change, rattling exhaust, and grooved rotors...hell even my rear rotors are grooved!!!! and they do 20% of the braking

shot of the rear rim, u can see the groves in the disc

Cobalt443

very similar to what mine look like

IneedHelp

WOW. Ill be checking my car often to see if this develops.

Keep us posted on how GM handles this problem pls.

I'm getting mine looked at tomorrow. The fronts are pretty bad, but the backs are ok. If they don't do anyhting about it, I'm gonna contact Uneek for a set of their cross drilled & slotted rotors and a set of pads. They have worked well for ExHondaMan.

The pads on the SS S/C are too hard for the rotors. All the other SS S/C's I've seen in AZ are grooved by 4,000-5,000 miles.

Grooving is 100% normal guys (and gal)...as long as the brakes aren't pulsing; no harm no foul. Also, GM will only replace them under warranty if the grooves are in excess of 1.5 mm deep.

best advice we probaly could give someone who is buying these cars, is to swap out the pads, my dealer was telling me these pads are what a grooving the rotars

STi_WRX02

Dealer should replace em' if not then bitch at em' and they should at least machine the rotors down smooth. Pads are the culprit but grooving is inevitable....just deal with it. If you end up getting performance pads, they wil do the same if not more than oem pads. I have 1500km on my new slotted rotors and ther are no grooves but I can already tell where the grooves will appear. Damn Hawk HPS pads! hhahah jk jk..they are good pads...

g5mike

is there a rotar out there that can stand up to these pads/

Tomtwtwtw

True. Rub your finger on the brakes (when they're cold obviously). If you can't feel any large grooves, and there's no shimmy or shake when you come to a stop, then it's just normal wear and tear. The rotors will tend to look a lot worse than they really are. Mine already look grooved, but when I feel them, they're smooth all across the surface, on both sides.

plyboy-illest

bring it intot he dealer they will mechine them for you under warenty

Cobalt443

well I dropped it off at the dealership to have the brakes fixed for the SECOND time and I get a call saying "It's normal wear and we can't duplicate the steering wheel shake or brake pulsation" and I say "well if it's normal wear then how come you fixed it the first time it occurred?" Of course I got dead air over the phone so I called GM directly and what does Mr. Bruce Mitchell say? Try taking it to another dealership. Now I honestly know why GM is going down the sh*t pipe..... not for making sh*tty cars but for sh*tty customer service. If I wasn't such a GM nutswinger I'd switch to another company solely for the fact that GM customer service and most of their dealers blow b*lls. That is all
