Brake Pedal Noise Ls 460

[scotthello]

Test drove the LS460 and noticed the brake pedal sounded very cheap when I released my foot from it. My other cars (Jeep & MB) both were quiet when took my foot off the brake pedal and the pedal went back to its normal position. Has anyone else noticed this "noise" when releasing the pedal. My other cars are quiet and seem like they have some type of pneumatic/gas control while the LS almost sounds like a toy pedal with a spring behind it snapping it back into postion! I have never heard anything like this before. I have the LS460h on order and am wondering if this is going to bother me or if i will get used to it?
