Narrative:

I was helping the purchaser of a BE55 get familiar with his aircraft. This was our first serious work on VFR patterns. We taxied to runway; I did our run-up and took off for a visual circuit. The plan was to do several full stop taxi back lndgs; both flaps up and flaps 30 degrees. His first landing was on touchdown zone (1000-1300 ft down the runway) left of centerline. He slowed the aircraft and exited the runway at A8. During the taxi on taxiway A8; the right brake failed and he drifted left of centerline. I applied full right rudder and announced 'I have control.' we exited the taxiway before he released the left brake. (In his aircraft the right seat has no brakes). The left propeller struck a taxiway light. I informed geu ground that we would taxi to park and taxied the aircraft to the ramp. Supplemental information from acn 694553: upon turning onto taxiway A8; right toe brake went to the floor; aircraft veered left and left propeller hit 2 taxi lights. Mei took over steering; we taxied to ramp and had aircraft towed to parking spot.
