I AM HAVING PROBLEMS WITH MY BRAKING SYSTEM. I HAD MY BRAKES FIXED IN FEBRUARY 2001, IT IS NOW 10/2001 AND I HAVE HAD THE BRAKES REPLACED AGAIN. I AM A SAFE DRIVER AND DO NOT DRIVE DANGEROUSLY OR WRECKLESS. I DO NOT UNDERSTAND HOW WEAR AND TEAR OCCURED SO QUICKLY. MY FRONT END VIBRATES VIGOROUSLY WHILE BREAKING. STOPPING SEVERAL FEET PAST THE POINT WHERE I BREAKED. THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR. I HAVE TO STOP WAY AHEAD OF A STOP. ALSO, MY CAR SHAKES AND THE BRAKE PEDAL VIBRATES WHEN I TRY TO STOP. AS FOR THE TRANSMISSION, WHILE DRIVING, THE CAR IS IDLED WAY ABOVE THE POINT WHERE IT SHOULD. THE CAR GIVE A BIG THUMP AND THROW FORWARD WHEN I AM TRYING TO BREAK. THE TRANSMISSION IS MAKING FUNNY NOISE, AS IF I AM DRIVING 55 MPH WITH THE CAR IN NEUTRAL. AS FOR THE FUMES, THEY COME IN MY CAR AND IS VERY UNSETTLING. I CAN NOT STAND THE WAY THE FUMES SMELL. THE CAR IS ALSO SMOKING.*AK
