I WAS IN LINE AT A FAST FOOD RESTAURANT AND AS I APPROACHED THE DELIVERY WINDOW, I BRAKE THE CAR TO 3 MPH, PREPARING TO STOP BEHIND THE CAR IN FRONT. MY FOOT WAS ON THE BRAKE, BUT I FELT THE BRAKE SUDDENLY GIVING WAY, HAVING A SPONGY FEEL AS IT WAS BECOMING INOPERABLE. THE CAR SURGED FORWARD AND HIT THE CAR IN FRONT OF ME. THIS WAS THE SECOND TIME THIS PRECISE THING HAS HAPPENED. THE EARLIER INCIDENT OCCURRED IN NOVEMBER, 2013, AND, THANKFULLY, EACH INCIDENT DID NOT INVOLVE HITTING A PEDESTRIAN. FORTUNATELY, THE RATE OF SPEED WAS VERY LOW, AS WELL, SO DAMAGE TO VEHICLES WAS SMALL. THESE INCIDENTS ALARMED ME FOR I COULDN'T HELP BUT THINK WHAT THE CONSEQUENCES COULD HAVE BEEN HAD I BEEN AT A RAILROAD CROSSING, APPROACHING A SCHOOL BUS DISCHARGING CHILDREN, ETC.. I TOOK THE CAR TO RICK CASE HYUNDAI IN PLANTATION, FLORIDA, TO HAVE THE CAR CHECKED OUT AND THEY SAID THEY FOUND NO PROBLEMS. THEY ALSO SAID THERE HAVE BEEN ABSOLUTELY NO RECALLS OR OTHER PROBLEMS INVOLVING BRAKES OR THROTTLE MALFUNCTIONS. SO, NOTHING WAS ACTUALLY SETTLED AS FAR AS WHATEVER THIS PROBLEM MAY BE, OR FIXING IT. *TR
