During the landing roll, the right brake seal failed on the experimental category, ex-military airplane, releasing the hydraulic fluid and subsequently rendering the brake unusable. The airplane encountered soft earth as it began to drift left, and ultimately departed the left side of the 3,700 feet long by 75 feet wide gravel runway. The nose gear then collapsed. The right brake system had been overhauled and the right brake seal replaced 15 hours prior to the accident.
Probable Cause: The failure of the recently overhauled right brake seal resulting in a total loss of brake fluid, failure of the right brake system, and subsequent inability of the pilot to utilize the brake. A contributing factor was the soft terrain.
