A pilot intentionally ground looped the airplane after the right brake failed during landing roll, unable to stop on remaining runway. Investigation found worn brake linings and hydraulic fluid leakage.

Incident Details

During the landing sequence, the pilot executed a normal approach and touched down within the landing zone as defined by the VASI system. However, upon initiating the landing roll, the pilot discovered that the right brake was inoperative. With the remaining runway insufficient to bring the aircraft to a stop while maintaining a straight path, the pilot shut down the engine approximately 1,000 feet from the end of the runway and deliberately performed a ground loop to bring the aircraft to a halt.

Investigation Findings

An investigation into the incident revealed that the brake linings had been worn down. Additionally, the brake piston had traveled beyond its normal range of motion, resulting in hydraulic fluid escaping from the brake system.
