The NTSB's narrative final · quoted from the NTSB record
The pilot reported that, when he applied wheel brakes during the landing roll, the airplane veered left. The airplane subsequently exited the runway and collided with a fence, which resulted in substantial damage to the right wing. Postaccident examination of the airplane's right brake assembly revealed two small cracks in the rigid portion of the hydraulic brake line. The cracks were seeping red fluid consistent with hydraulic fluid. The breach in the hydraulic brake line and loss of fluid likely resulted in a loss of hydraulic pressure, which rendered the brake system inoperative.
