I WAS IN STOP AND GO MORNING RUSH HOUR TRAFFIC GOING APROX. 10 MPH. I PRESSED THE BRAKE TO STOP SLIGHTLY MORE THAN ONE CAR LENGH AWAY FROM THE CAR IN FRONT OF ME. THE BRAKES FELT SOFT AND I HAD TO PRESS THE BRAKE PEDEL ALL THE WAY TO THE FLOOR TO GET IT TO RESPOND. THE BRAKES DID NOT CATCH ALL THE WAY, THEY ONLY SLOWED THE CAR SLIGHTLY (TO APROX. 5MPH) AND I REAR-ENDED THE CAR IN FRONT OF ME. I HAD THE BRAKES, FLUID, AND ELECTRICAL/COMPUTER COMPONENTS CHECKED, AND THEY COULD NOT FIND ANYTHING WRONG WITH THE CAR. *TR
