It is not her imagination nor is it mine. I have the same exact issue with my Camaro. I am not able to grasp that this is normal. I have the Brembo brakes as well I thought maybe they were pulled to tight seems that is not the case. I think I will do a little more research on the brakes. That said the common element for me seems to be incline. I do park at home and at work on a slight incline albeit opposite directions in each case. I am also wondering if temperature is a contributing factor because I do seem to notice it more in the morning and after work. Since I live in Texas and we are in August if it is tied to temperature it is scary.
Thanks for validating my sanity.
If I hear or read anything I will be sure to come back and let you know.
