I was taxi testing the aircraft. I taxied to [the] runway; then turned around and taxied back to the ramp. I lost brakes and taxied into another aircraft. The damage to the other aircraft was minimal; and I broke my taxi light on my left wing.
C172 pilot reported taxiing into another aircraft following brake failure.
