I have tried turning off the Automatic Parking Brake by pulling the Parking Brake switch. The manual says that if you pull it and hold it for a few seconds the parking brake goes into manual mode. My 2008 and 2012 LS460s both had problems with the Parking Brake being set on auto. Over time it left indentations on the rotors.

Anyone have any opinions to offer on what I am doing wrong?

Thanks!
