I WAS DRIVING ON MY RESIDENTIAL STREET AND STEPPED ON THE BRAKE TO SLOW DOWN TO MAKE A LEFT TURN INTO MY DRIVEWAY. THE CAR FAILED TO SLOW DOWN OR STOP, AND INSTEAD WENT OVER THE CURB, VEERING TO THE RIGHT AND SIDE SWIPED THE LEFT SIDE OF MY NEIGHBOR'S CAR, NARROWLY MISSING HIS GARAGE.THE CAR THEN SIDE SWIPED A TREE ON MY LEFT (ON PROPERTY BETWEEN MY AND NEIGHBOR'S PROPERTY.) THE FRONT END OF THE CAR CRASHED INTO A TREE, SAVING ME FROM ROLLING ABOUT 900 FEET TO THE STREET BELOW. THE ENTIRE TIME OF THIS INCIDENT THE BRAKES NEVER ENGAGED (PEDAL WAS DOWN TO FLOOR) AND I FRANTICALLY TRIED TO STEER TO AVOID HITTING ANYTHING. A WITNESS, STANDING ON THE STREET, CONFIRMED MY BRAKE LIGHTS WERE ON. CAR WAS SERVICED BY TOYOTA (WORLD CLASS INSPECTION) 15 DAYS BEFORE THE INCIDENT. INSPECTION REPORT INDICATED BRAKE FLUID LEVEL AND BRAKE LINING WERE "CHECKED AND OK." AFTER THE INCIDENT THE CAR WAS TOWED TO A REPAIR SITE WHERE THE OPERATOR DEMONSTRATED TO ME THAT THE BRAKES WERE NONEXISTENT AND THE BRAKE FLUID LEVEL WAS STILL APPROPRIATE. CAR WAS DEEMED TOTALED. *TR
