Thanks for your help, I was thinking it was the brakes and probably is. I'm not sure how many miles are on the brakes, I haven't had the car all that long. Another question is.... The car makes a nasty vibrating noise almost a clanking sound from what seems to be coming from the catalytic converter. It seems to do this while its cold before warming up. Loose exhaust or what?? Sorry for all the questions but I'm a woman who loves the car but doesn't know a thing about it!!!
