Rotors

So since i have had my 07 g6 gt (I've owned it for about 6 years) almost every year and a half I put on new rotors. Does anyone else have this issue? It just seems like they should be lasting longer than that or am I crazy? Any input would be appreciated

Don't buy factory OEM rotors. They are crap. Get a set of good after-market ones and make sure your lug nuts are tightened to exact torque specification. Or just go with rotors made in China. They are just as good as OEM ones but much cheaper, and you don't need to machine them.

I disagree with mrslcom. I never had issues with oem rotors. I did find cheap Chinese rotors to be crap. And by the way, you should't need to machine ANY new rotors. If they're not flat, they're the worst of the worst quality and you should return them.

kerikay, you didn't say why you keep having to replace rotors. Do they warp? Which ones? Front, rear or both?

They warp. i did have the last set I put on turned when i could tell they were getting bad again bc they werent total junk, and I didnt want to spend the money again on new ones. But I only did that once. And its specifically the front rotors. My boyfriend just feels like we have replaced them to many times compared to any other vehicle I've had. Just thought I'd seek out advise on the forums to see what could help.

It's very common for our stock rotors to warp. It's been an ongoing problem for as long as I can remember. I upgraded to some R1 concepts rotors about 100,000 miles ago and have never had any problems.

That may be. But she says they have replaced them multiple times. It's very unlikely that different brands and/or production runs several years apart would have the same issue. I would suspect some issue other than the rotors. Like hydraulic pressure not releasing properly and dragging the brakes.

kerikay, do you wear out the brake pads unusually fast?

I'm not seeing the logic of that. They have a problem that's pretty clearly NOT the rotors or calipers and that's exactly the parts you want to replace? Why?

they are warping because they are stopping too quickly and getting the brakes too hot.larger brakes should help.

How did you decide they are stopping too quickly and overheating the brakes? The OP did not mention it. It would take a lot of panic braking, repeatedly, to do that. She needs to give more details, but said nothing about autocrossing the car. LOL.

Also, don't forget there is a 400-500lb weight difference between the sedan/coupe and convertible. I have a convertible and have not managed to overheat the brakes. If the car in question is NOT a convertible, they are almost 500 lbs lighter and it would be very hard to overheat the stock brakes in everyday normal use.

Power Stop K1610 Front Z23 Evolution Brake Kit with Drilled/Slotted Rotors and Ceramic Brake Pads
Amazon $162.
Drilled and slotted rotors. They stop the car much better than stock, no fade, no warping rotors.
Best thing I ever added to the G6 as it offsets the extra weight of the convertible.

Hi...I too had a similar problem with my 07 GT cnvt. They were going out at about 20-25k miles (3 times). My normal is 60-70k (or more) in other cars. I do not drive hard, brake hard, autocross, etc.
Went to drilled and slotted nickel plated rotors and ceramic pads. What a difference. That has been 50k miles ago. The nickel plating wears off on the rotor right away, but then the rotors always look nice and shiny. The rest of the rotor though, remains nickel plated (silvery) and does not rust.

Buzz, what is the brand? Do you have a link? I've seen many types of plating, but never nickel.

I could not locate the actual vendor from where I purchased several years ago, but did find very similar units from Power Sport on eBay. BUT they have zinc plated, not nickel.
