Recently. a brake fire was reported which was eft-usedby a ruptured brake

piston. The fire was quickly extinguished but caused damage to the paint

and hydraulic/electrical harness and its componbnts. Detailed investigation

showed that a hydraulic lock must have been prbsent close to the affected

brake creating enough internal pressure to ruptt&e the piston. The most

probable scenario for the hydraulic lock is a locrened (not necessarily

disconnected) brake QD [quick-disconnect] coLWling.Further

investigation of the service experience files at Rokker Services showed

that more brake fires have occurred on aeropl es in a pre-mod SEFt 00-

32-127 configuration.
