Narrative:

Our company operates a ram conversion, liquid cooled C414 as a 2 pilot airplane -- although legally it is single pilot. I was the PNF, but retain PIC responsibility. We were taxiing on the parallel taxiway for runway 33 at int and nearing the hold short threshold line. As the PF attempted to stop, he had no right brake actuation or 'live pedal.' as this is a castering nosewheel, the aircraft immediately turned left. I (PNF) immediately applied full right brake/pedal with no actuation. We stopped just off of the taxiway and now had full brake authority/authorized on both left and right and both PF and PNF position. We requested permission to taxi back to an apron area to inspect the aircraft. After inspecting and taxi testing the aircraft, we could not reproduce the malfunction. We continued to roc with no further indications. As a precaution, we had the brake system flushed. It is the crew's belief that the combination of a long downhill taxi and a cold soaked aircraft may have been causal (ice at master cylinder). Stopping, even though it meant leaving the taxiway, was the only course of action, as the aircraft could not be allowed to continue straight ahead. There was no damage to the aircraft, airport lighting, and no complaints from the tower. I don't know if there was a 'foul,' but we thought that you should know.

Title: A C414 FLT CREW EXITS THE TXWY WHEN LOSING BRAKING TO THE R GEAR AT INT, NC.

Narrative: OUR COMPANY OPERATES A RAM CONVERSION, LIQUID COOLED C414 AS A 2 PLT AIRPLANE -- ALTHOUGH LEGALLY IT IS SINGLE PLT. I WAS THE PNF, BUT RETAIN PIC RESPONSIBILITY. WE WERE TAXIING ON THE PARALLEL TXWY FOR RWY 33 AT INT AND NEARING THE HOLD SHORT THRESHOLD LINE. AS THE PF ATTEMPTED TO STOP, HE HAD NO R BRAKE ACTUATION OR 'LIVE PEDAL.' AS THIS IS A CASTERING NOSEWHEEL, THE ACFT IMMEDIATELY TURNED L. I (PNF) IMMEDIATELY APPLIED FULL R BRAKE/PEDAL WITH NO ACTUATION. WE STOPPED JUST OFF OF THE TXWY AND NOW HAD FULL BRAKE AUTH ON BOTH L AND R AND BOTH PF AND PNF POS. WE REQUESTED PERMISSION TO TAXI BACK TO AN APRON AREA TO INSPECT THE ACFT. AFTER INSPECTING AND TAXI TESTING THE ACFT, WE COULD NOT REPRODUCE THE MALFUNCTION. WE CONTINUED TO ROC WITH NO FURTHER INDICATIONS. AS A PRECAUTION, WE HAD THE BRAKE SYS FLUSHED. IT IS THE CREW'S BELIEF THAT THE COMBINATION OF A LONG DOWNHILL TAXI AND A COLD SOAKED ACFT MAY HAVE BEEN CAUSAL (ICE AT MASTER CYLINDER). STOPPING, EVEN THOUGH IT MEANT LEAVING THE TXWY, WAS THE ONLY COURSE OF ACTION, AS THE ACFT COULD NOT BE ALLOWED TO CONTINUE STRAIGHT AHEAD. THERE WAS NO DAMAGE TO THE ACFT, ARPT LIGHTING, AND NO COMPLAINTS FROM THE TWR. I DON'T KNOW IF THERE WAS A 'FOUL,' BUT WE THOUGHT THAT YOU SHOULD KNOW.
