Hydraulically actuated brake controller?
Being somewhat obsolete myself, I found a NOS hydraulically actuated brake controller at a small town auto parts store. I have had them before on older vehicles and they work quite well. I have a '97 ...

If it's an old actuator which has a piston moving a potentiometer, than its probably a no-go. The newer ABS systems can be very sensitive to any extra fluid displacement. I'm not sure how much is OK, but its very little on the Ford/Bendix system.
The newer hydraulic actuators use a pressure transducer (like MaxBrake) so there isn't any extra fluid displacement, making it compatible with ABS.
Also keep in mind than most older brake controllers won't work with trailer disc brakes, which are slowly making their way into the market. Some of the new high-end fivers now have them, and they are becoming a more common aftermarket upgrade.
