......I think mine are but I'm not sure. It can just be paranoia but I still want be sure my car is still in perfect working order. Someone please advise. Thank you....

 

go about 120mph and brake...don't slam on the brakes, but brake fairly hard as if you need to stop completely in about 1/8 mile or so...if you feel cla-clunk-cla-clunk (like rolling a ball that isn't perfecly round (oval) down a bowling alley)...if you feel it and hear it you will know...if it just brakes flawlessly and normally, you are fine...anything over 100mph should be a good test

 

if you feel any shaking in the steering wheel or brake pedal, you've got them. It gets worse after the brakes are hot.
It didn't happen to mine till about 9000 miles

 

A good way to warp your rotors is to try to stop from over 100. Anyway, if you have vibration at a specific speed, then a wheel is out of balance or alignment. If you have the vibration the entire time you are decelerating, then its your brakes. The pad may not line up with the rotor correctly or the rotor itself may be warped. When you wash your car, if you get water on your brakes after any good use, you can warp your rotors. I did it to mine two weeks ago, but I figure that I'll get cross-drills in the spring with my new rims, so I'll just live with it. How many miles do you have anyway?
