I am just curious, on average how often do you have to have your automobile brakes serviced? My brakes just went on my 2004 Malibu, normally you have some indication that they are running thin but this time they just went right to the metal. All I can say is OUCH, the repair bill was not cheap, so soon after the holidays too.. This is the first time this ever happened, had the car inspected in the fall and everything was great. Is it unusual to wear down your brake pads in 4 months?
