The NTSB's narrative final · quoted from the NTSB record
During an instructional flight, the student pilot reduced engine power to idle and applied the brakes as the airplane taxied toward the end of the runway. However, the airplane did not respond to this brake application. The flight instructor assumed control of the airplane and applied brakes, but the airplane still did not respond. While the flight instructor was attempting to mitigate the situation, the airplane exited the right side of the taxiway and impacted a ditch. Examination of the airplane’s brake system revealed a leak on both main landing gear brake caliper O-ring seals. Both brake calipers were removed and disassembled, and both O-ring seals were flattened, consistent with excessive use and wear. The flattened O-ring seals prevented the proper seal within the brake calipers, which resulted in the complete loss of brake fluid. The complete loss of brake fluid prevented the use of the airplane brakes, which caused a subsequent loss of directional control.
