Brake pedal goes way down to almost floor before working
My brakes work, but I have to push the pedal down far before they work. The front brakes were replaced a month or two ago. It doesn't seem related to that repair since this wasn't a problem at that time. It's making me nervous. In the past I would assume the brakes need bleeding, but I've seen enough to ask if it could be something else. We're taking it in tomorrow, but just kind of curious what you guys think it could be.
