BRAKE FAILURE. BRAKE PEDAL WENT COMPLETELY TO THE FLOOR AND VEHICLE DID NOT STOP UNTIL IT HIT A TREE. I PRESSED THE BRAKE, STARTED THE CAR. THE BRAKE PEDAL DID NOT FEEL ABNORMAL. WITH MY FOOT STILL ON THE PEDAL, I PUT THE VEHICLE IN REVERSE. THE PEDAL IMMEDIATELY WENT SOFT AND COMPLETELY TO THE FLOOR. SINCE I WAS IN MY DRIVEWAY ONLY PLANNING TO MOVE THE VEHICLE BACK ABOUT 3 FEET, I DID NOT CLOSE THE DOOR. WHEN THE VEHICLE DID NOT STOP, ITS DOOR CAUGHT A TREE AND BENT BACKWARDS INTO THE FRONT FENDER. THE VEHICLE STOPPED BECAUSE THE DOOR CAUGHT THE TREE. THE ONLY WARNING DISPLAYED ON DASHBOARD WAS THAT THE DOOR WAS OPEN AND THE CAR WAS NOT IN PARK. AFTER INCIDENT I TURNED ON POWER TO VEHICLE WITHOUT STARTING TO RECORD THE MILEAGE ON THE VEHICLE FOR MY INSURANCE COMPANY AND THAT IS WHEN THE LOW BRAKE FLUID WARNING CAME ON. *TR
