My girlfriend just bought a 2002 turbo GLS (like two days ago). On the test drive the brakes worked just fine, but after her first full day the brakes won't engage properly. Usually they will work alright, but every so often going forwards or in reverse she can stand on them and barely slow down. I'm no car guy, but everything looks fine and the dealer says the brakes are all of two weeks old. It's not actively unsafe as I can stop within a foot of where I intended to, but I have experience with driving on poor brakes...but it's worrisome and she's not as confident as I am. And I have my own beetle to drive that I want back. Any suggestions?
