Aircraft
I was Captain and pilot flying. I was flying a normal approach (Visual) to Runway 7. After fully configuring the aircraft we continued to land. Upon touching down the main gear I lowered the nose wheel onto the runway; deployed the thrust reverses and applied the main brakes. I felt that I had no pressure pushed on the brakes again and I announced that; 'I have no brakes going to emergency braking; I've lost my steering.' As I gently pulled on the emergency brake handle my co-pilot reengaged the steering and reached over and extended the spoilers manually to ensure they were extended. I stated that emergency braking wasn't working and pulled a little firmer and said that I've still got no steering. The steering was reengaged but I didn't have any directional control at this time. My co-pilot said don't skid and I felt the plane start to go sideways. I kept holding the brake handle until we did come to a complete stop facing the opposite direction. At this point I shut down the plane and contacted Clearance Delivery to let them know that we were on the runway and that Runway 7-25 was closed as we could not move and then I called the owner. After shutting down the engines I could still hear something running; I looked over the panel and deduced that it was the Aux Hyd Pump. I shut this down and secured the aircraft. At this point we exited the aircraft and walked around the aircraft to assess for any damage. I pushed down the spoilers manually at this time. I then discussed with my copilot the approach and landing trying to understand what had just happened. The only conclusion that I had was that I lost my main brakes; my emergency brake wasn't effective and that I didn't have directional control. I have since spoken with the Maintenance Department; management and my co-pilot to figure out what had happened; I have also looked at what I can do differently in this situation to have a better out come.
A LR45 normal brake; emergency brakes and steering failed on landing. The steering reengaged but caused a 180 on the runway but came to a complete stop after which ATC was called to close the runway.
