Narrative:
Departing ZZZZ international airport, our parking brake failed to fully disengage. No light or audible signal indicated this condition. Our only indications were as such: our takeoff roll was slightly longer than anticipated. However, taxiing was normal and since outside air temperatures were nearly 40 degrees C, near the edge of our performance limitations, this did not immediately appear abnormal. Upon rotation, there was more than usual acceleration. Climb out and cruise were normal. A cursory check of parking brake position showed that the handle was up 1/4 - 3/8 inch, a tiny distance of its overall travel and barely above its lowest (disengaged) position. Spring tension on this handle ceased well before its lowest position and the light extinguishes before that. The handle has 1 detent -- fully on. Common sense would lead one to conclude that the brake was completely off and there was another cause. All system were checked and appeared normal. Concerned with a stuck brake and possible blown tire and subsequent skid, we elected to land in ZZZZ1 with its over 13000 ft runway. Upon landing, it was immediately obvious there was some type of failure. No response from brakes and loud noise and vibration. I elected not to deploy lift-dump system and use aerodynamic forces to maintain directional control. The outcome was successful and the aircraft coasted to stop using approximately 8000 ft of runway. Damage to aircraft was confined to wheels, tires and brakes. No injuries. Inspection has led to a preliminary conclusion. While the parking brake may look, feel, and indicate 'off,' it may still be on slightly. This light pressure on the brakes can cause excessive heat on takeoff roll that would allow fuse plugs to open and deflate tires after takeoff. Callback conversation with reporter revealed the following information: the reporter stated the cause of the parking brake failure is still under investigation by raytheon, the manufacturer. The reporter said there was no audible or parking brake light warning and the only thing noted was the parking brake handle was 1/4 - 3/8 inch out of normal off position. The reporter stated the handle has 1 detent and that is fully on.

Title: A BEECH PREMIER 1 ON LNDG EXPERIENCED LOUD NOISE AND VIBRATION. DAMAGED BRAKES AND TIRES. PRELIMINARY FINDINGS INDICATE THE ACFT TOOK OFF AND LANDED WITH PARKING BRAKE ON.
Narrative: DEPARTING ZZZZ INTL ARPT, OUR PARKING BRAKE FAILED TO FULLY DISENGAGE. NO LIGHT OR AUDIBLE SIGNAL INDICATED THIS CONDITION. OUR ONLY INDICATIONS WERE AS SUCH: OUR TKOF ROLL WAS SLIGHTLY LONGER THAN ANTICIPATED. HOWEVER, TAXIING WAS NORMAL AND SINCE OUTSIDE AIR TEMPS WERE NEARLY 40 DEGS C, NEAR THE EDGE OF OUR PERFORMANCE LIMITATIONS, THIS DID NOT IMMEDIATELY APPEAR ABNORMAL. UPON ROTATION, THERE WAS MORE THAN USUAL ACCELERATION. CLBOUT AND CRUISE WERE NORMAL. A CURSORY CHK OF PARKING BRAKE POS SHOWED THAT THE HANDLE WAS UP 1/4 - 3/8 INCH, A TINY DISTANCE OF ITS OVERALL TRAVEL AND BARELY ABOVE ITS LOWEST (DISENGAGED) POS. SPRING TENSION ON THIS HANDLE CEASED WELL BEFORE ITS LOWEST POS AND THE LIGHT EXTINGUISHES BEFORE THAT. THE HANDLE HAS 1 DETENT -- FULLY ON. COMMON SENSE WOULD LEAD ONE TO CONCLUDE THAT THE BRAKE WAS COMPLETELY OFF AND THERE WAS ANOTHER CAUSE. ALL SYS WERE CHKED AND APPEARED NORMAL. CONCERNED WITH A STUCK BRAKE AND POSSIBLE BLOWN TIRE AND SUBSEQUENT SKID, WE ELECTED TO LAND IN ZZZZ1 WITH ITS OVER 13000 FT RWY. UPON LNDG, IT WAS IMMEDIATELY OBVIOUS THERE WAS SOME TYPE OF FAILURE. NO RESPONSE FROM BRAKES AND LOUD NOISE AND VIBRATION. I ELECTED NOT TO DEPLOY LIFT-DUMP SYS AND USE AERODYNAMIC FORCES TO MAINTAIN DIRECTIONAL CTL. THE OUTCOME WAS SUCCESSFUL AND THE ACFT COASTED TO STOP USING APPROX 8000 FT OF RWY. DAMAGE TO ACFT WAS CONFINED TO WHEELS, TIRES AND BRAKES. NO INJURIES. INSPECTION HAS LED TO A PRELIMINARY CONCLUSION. WHILE THE PARKING BRAKE MAY LOOK, FEEL, AND INDICATE 'OFF,' IT MAY STILL BE ON SLIGHTLY. THIS LIGHT PRESSURE ON THE BRAKES CAN CAUSE EXCESSIVE HEAT ON TKOF ROLL THAT WOULD ALLOW FUSE PLUGS TO OPEN AND DEFLATE TIRES AFTER TKOF. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE CAUSE OF THE PARKING BRAKE FAILURE IS STILL UNDER INVESTIGATION BY RAYTHEON, THE MANUFACTURER. THE RPTR SAID THERE WAS NO AUDIBLE OR PARKING BRAKE LIGHT WARNING AND THE ONLY THING NOTED WAS THE PARKING BRAKE HANDLE WAS 1/4 - 3/8 INCH OUT OF NORMAL OFF POS. THE RPTR STATED THE HANDLE HAS 1 DETENT AND THAT IS FULLY ON.
