OK, I think something needs replacing then, because they squeak louder when I press harder... if I do it lightly then I can kind of mask the noise, but it sucks having to drive with the feeling that you can't stop because of how loud and obnoxious the noise is. I'm going to take it in to a shop. Any authorized Porsche dealership should be good right? I'm in Tampa, FL.
I don't know any technical details about the situation or I would respond to your guys' questions. I appreciate the help though
