Narrative:
While in cruise at 14000 ft, the aircraft had a hydraulic failure on the 'green' side. This affects normal braking and landing gear. The cause was a low level, so xfeed was not an option. We performed all emergency checklists that applied. We advised approach at ord we had no normal braking and asked for 'the equipment' to 'stand by.' passenger were advised. Gear was extended via emergency extension procedures. Normal landing performed with reverse and emergency braking. Normal taxi with extreme caution to the gate.
