To start, I have a 97 Sunfire GT. I bought the car with it having the ABS and BRAKE lights on. Before purchasing the car I visually checked the pads and rotors. Pads are almost brand new and the rotors dont have any grooves, etc in them. I use my vehicle for work in which I drive about 200 miles a day all in the city of Charlotte. I have noticed that the brakes go "hard" after what I would consider a short amount of time. Is this a sensor issue or something more dramatic. Opinions please? Thank you
