While taxiing the cessna 414, from the left seat and under supervision and instruction from the qualified rated pilot in the right seat, the brakes failed as the aircraft approached the parking area. I immediately advised the PIC who took control of the aircraft. There were no brakes on his side either, and he then shut down both engines by pulling the mixture levers to idle cutoff. We continued to apply brake pressure and attempted to turn the aircraft, but were not successful. It coasted into another parked aircraft causing minimal damage. This occurrence did not involve any 'intention of flight,' but was only a repositioning from one FBO to another. Since the failure was mechanical, I do not believe anything would have prevented the occurrence.

Title: WHILE TAXIING THE CESSNA 414 FROM THE L SEAT AND UNDER THE SUPERVISION OF THE QUALIFIED PLT IN THE R SEAT, THE BRAKES FAILED AS THE ACFT APCHED THE PARKING AREA. THE QUALIFIED PLT TOOK CTL OF THE ACFT. THERE WERE NO BRAKES ON HIS SIDE OF THE ACFT EITHER. HE SHUT DOWN BOTH ENGS, ATTEMPTED A TURN, BUT WAS UNSUCCESSFUL IN AVOIDING COLLIDING WITH ANOTHER ACFT.

I IMMEDIATELY ADVISED THE PIC WHO TOOK CTL OF THE ACFT. THERE WERE NO BRAKES ON HIS SIDE EITHER, AND HE THEN SHUT DOWN BOTH ENGS BY PULLING THE MIXTURE LEVERS TO IDLE CUTOFF. WE CONTINUED TO APPLY BRAKE PRESSURE AND ATTEMPTED TO TURN THE ACFT, BUT WERE NOT SUCCESSFUL. IT COASTED INTO ANOTHER PARKED ACFT CAUSING MINIMAL DAMAGE. THIS OCCURRENCE DID NOT INVOLVE ANY 'INTENTION OF FLT,' BUT WAS ONLY A REPOSITIONING FROM ONE FBO TO ANOTHER. SINCE THE FAILURE WAS MECHANICAL, I DO NOT BELIEVE ANYTHING WOULD HAVE PREVENTED THE OCCURRENCE.
