brakes on a 2007 impala

6 posts in this topic

I have the warped rotor wobble when i use the brakes on my 2007 Impala. Its not that bad yet so i want to nip it before it gets worse.

From what i can tell the pads are still good. can i just take the rotors off and have them turned, and put all back together? I've done them a bunch of times on my pickups over the years, but they were older, is there anything special with particular car i need to watch out for? I am only doing the front 2.

You should be able to bring yours into get them machined, but it wont be as good as having them done on the car.

Also don't be surprised if they are not thick enough to be turned.

I think a 13mm and a 15mm are all that is needed to get the caliper of. If your just turning the rotors you can remove the 2 bolts that hold the bracket into place and remove the caliper and bracket in one assembly. Make sure to torque the lug nuts when your done. Improperly torquing or the lack there of can lead to them warping again. Also keep in mind that you can make a rotor true but you can never take the warp out of a rotor. The likely hood of them warping again if turned and properly installed is slim but it can happen.

sounds like its somethign i can handle. What ft-lbs do lugs nuts need to be torqued to? Im sure the place that rotates my tires doesnt torque properly, they jsut hammer on it with the impact and call it good.

Page 406 of your owners manual, 100 lb-ft.

Next time you see them put on the tires see if there using a grey or blue extension on there impact that is about 8 inches long when they put the tires back on. If so they are using a torque stick which has become very common. I have been using them for over ten years with very few comebacks for lose tires (zero loose tires) or warped rotors.
