Narrative:
The 35-hour student pilot stated that he was aware that he was landing downwind, but feared that he might have lost visual contact with the airport due to the fog that was forming, if he had attempted to circle the airport to land on runway 3. The pilot reported the winds from 030 degrees at 15 knots and stated that he touched down midfield on the 4,800-foot runway. During the landing roll, he started to apply the wheel brakes as he approached the departure end of the runway. While applying brake pressure with the brake lever, the cable to the brakes snapped resulting in the total loss of braking action. The airplane overran the departure end of the runway, and the nose wheel impacted a ridge/terrace in the wheat field adjacent to the airport. The 1961 model 'Colt' had accumulated a total of 1,715 airframe hours. According to the manufacturer's illustrated parts catalog, the failed cable assembly for the brake control, part number 40123-91, is a condition item without a specific replacement or retirement time. The cable separated at the point where it makes a sharp turn over a pulley (part number 11200-00).

Probable Cause: The loss of wheel brakes due to the failure of the brake actuating cable. A factor was the tailwind.
