Narrative:

During my preflight walk-around and inspection of aircraft logbook, I found the aircraft to be in airworthy condition and no open logbook write-ups. Shortly after arriving at iah, a maintenance representative entered the cockpit and asked if we knew there was a hydraulic brake line disconnected. We did not! During my next walk-around I observed maintenance personnel working around the brake area. We assumed that maintenance had reconnected the brake and we departed iah en route to lax. This flight also operated normally and after arriving at lax, my crew went to the hotel for remain overnight. I have since learned that the brake line had not been connected in iah as we thought. At this time, I'm not sure when this brake was re-connected.

Title: A WDB SO ALLOWED HIS ACFT TO FLY 2 LEGS WITH A WHEEL BRAKE HYD LINE DISCONNECTED.

Narrative: DURING MY PREFLT WALK-AROUND AND INSPECTION OF ACFT LOGBOOK, I FOUND THE ACFT TO BE IN AIRWORTHY CONDITION AND NO OPEN LOGBOOK WRITE-UPS. SHORTLY AFTER ARRIVING AT IAH, A MAINT REPRESENTATIVE ENTERED THE COCKPIT AND ASKED IF WE KNEW THERE WAS A HYD BRAKE LINE DISCONNECTED. WE DID NOT! DURING MY NEXT WALK-AROUND I OBSERVED MAINT PERSONNEL WORKING AROUND THE BRAKE AREA. WE ASSUMED THAT MAINT HAD RECONNECTED THE BRAKE AND WE DEPARTED IAH ENRTE TO LAX. THIS FLT ALSO OPERATED NORMALLY AND AFTER ARRIVING AT LAX, MY CREW WENT TO THE HOTEL FOR REMAIN OVERNIGHT. I HAVE SINCE LEARNED THAT THE BRAKE LINE HAD NOT BEEN CONNECTED IN IAH AS WE THOUGHT. AT THIS TIME, I'M NOT SURE WHEN THIS BRAKE WAS RE-CONNECTED.
