The NTSB's narrative final · quoted from the NTSB record

The pilot said approaching dusk reduced visibility, and he decided not to continue his trip. He landed at Heber Valley Airport. As he applied brakes, the airplane veered to the right. The left wing struck the runway, and the airplane ground looped. A trail of brake fluid was found on the runway. The left brake line had separated from the caliper assembly. The threads were stripped out. There was no loop, or slack, in the brake line. The airplane had brake work done a year before the accident.
