Narrative:
Upon landing from a VOR/visual approach; the crew observed the aircraft; after touchdown on runway; begin an uncommanded maximum anti-skid stop. Additionally; the aircraft experienced a nosewheel steering failure at the same time. After coming to a complete stop; we were unable to move the aircraft any further due to the uncommanded brake pressures still evident. The control tower radioed the 'do you request assistance' call. We declined; and called our maintenance department to assist with the towing of the aircraft off the runway. The post-flight inspection did not yield any clues to the cause; and no damage was noted from the unusual landing event.callback conversation with reporter revealed the following information: the anti-skid control box on this aircraft controls both anti-skid and nosewheel steering; and should have annunciated its failure. The problem was remedied by replacing the anti-skid control box.

Title: GV CAPT RPTS UNCOMMANDED MAX ANTI-SKID STOP AFTER LNDG WITH SIMULTANEOUS NOSE STEERING FAILURE.
Narrative: UPON LNDG FROM A VOR/VISUAL APCH; THE CREW OBSERVED THE ACFT; AFTER TOUCHDOWN ON RWY; BEGIN AN UNCOMMANDED MAX ANTI-SKID STOP. ADDITIONALLY; THE ACFT EXPERIENCED A NOSEWHEEL STEERING FAILURE AT THE SAME TIME. AFTER COMING TO A COMPLETE STOP; WE WERE UNABLE TO MOVE THE ACFT ANY FURTHER DUE TO THE UNCOMMANDED BRAKE PRESSURES STILL EVIDENT. THE CONTROL TOWER RADIOED THE 'DO YOU REQUEST ASSISTANCE' CALL. WE DECLINED; AND CALLED OUR MAINT DEPARTMENT TO ASSIST WITH THE TOWING OF THE ACFT OFF THE RWY. THE POST-FLT INSPECTION DID NOT YIELD ANY CLUES TO THE CAUSE; AND NO DAMAGE WAS NOTED FROM THE UNUSUAL LNDG EVENT.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE ANTI-SKID CONTROL BOX ON THIS ACFT CONTROLS BOTH ANTI-SKID AND NOSEWHEEL STEERING; AND SHOULD HAVE ANNUNCIATED ITS FAILURE. THE PROBLEM WAS REMEDIED BY REPLACING THE ANTI-SKID CONTROL BOX.
