I just wanted to share my appreciation for this website. Long story short. I was away on business for several months. My wife wanted to do something nice for me while I was gone. She took my LC to the dealer and asked them to do whatever maintenance was needed. 100 bucks later they said that all was good. When she told me, I said BS, there's a warped rotor. So, she took it back and they said the rotors were fine. They charged another 100 bucks because they didn't find anything. I read some comments on this site that rear rotors are prone to warping and while I thought that was very unlikely, I put my money where your mouth is and ordered rotors and pads for the rear. Two hours later the brake issues were gone. Thanks.
