Narrative:

A week before the incident; I noticed fluid around my left (pilot side) brake. I notified my mechanic. [A week later] I called my mechanic and he told me the repair had been done. I then pre-flighted the plane; including brake check; and began to taxi along the hangar row towards the taxiway leading to runway xx at ZZZ. At approximately 100 yards; before reaching the taxiway; the plane began to veer to the right. I applied normal pressure on the left brake to correct the direction of the plane. My foot went to the floor (brake failure). I continued to apply pressure on the left brake 3 or 4 times; to no avail. I then pulled the power and applied pressure on the right brake; the only brake working. I managed to slow the aircraft to approximately 2 mph before impacting [a] hangar door. I do have a witness who came into the cockpit and saw my left brake/rudder pedal to the floor. There were no injuries.
