The firewas quickly extinguished but caused damage to the paint and hydraulic/electrical harness and its componbnts. Detailed investigation showed that ahydraulic lock must have been prbsent close to the affected brake creating enough internal pressure to rupttðe piston. The most probable scenario forthe hydraulic lock is alocrened (not necessarily disconnected) brake QD [quick-disconnect] coLWling.Further investigation ofthe service experience files atRokker Services showed that more brake fires have occurred on aeropl es in apre-mod SEFt 00- 32-127 configuration.
