REFLECTOR: Speed Brake

[Scott Baker]

Hello John,
Unless your aircraft has something other than standard factory 
equipment, the speed brake is operated by an electric linear actuator 
(no hydraulics).
The speed brake actuator opening in the floor of the aircraft is serving 
as an exit place for a leak in the hydraulic system.
Remove the keel cover(s) and keel inspection plates - grab a flashlight, 
mirror, and clean rag - and begin searching for puddles and drips.
If you are lucky, it will be a loose hose fitting.  If the cause is bad 
cylinder seal, it is reasonably easy to fix.  This will likely involve 
removing the cylinder from the aircraft for service.
Good luck!
Scott B.
