“MY VEHICLE WAS MOVING ABOUT 10 M.P.H. IN PREPARATION TO STOP BEHIND SEVERAL VEHICLES AT A RED LIGHT. I APPLIED MY BRAKES IN AN ATTEMPT TO COME TO A COMPLETE STOP; HOWEVER, THE BRAKES FAILED TO ENGAGE. I THEN PUT FULL PRESSURE ON THE BRAKE PEDAL. THE PEDAL WENT DOWN ALMOST TO THE FLOOR, BUT THE BRAKES FAILED TO STOP THE VEHICLE. AS A RESULT OF THIS BRAKE FAILURE, MY VEHICLE STRUCK THE VEHICLE IN FRONT OF IT WHICH IN TURN STRUCK A THIRD VEHICLE. MY VEHICLE WAS TOWED TO A MECHANIC WHO WAS ABLE TO DUPLICATE THE FAILURE. AT THIS TIME HOWEVER, HE IS UNABLE TO DETERMINE WHAT IS CAUSING THE FAILURE.*AK”
