Purchased replacement elbow. Right side appeared to stop leaking; before draining system, brakes were tested. Both gradually lost pressure; not good. Drained system; right side draining very slowly; reason unknown. Purged system gently with compressed air to remove remaining brake fluid. Removed right fitting; cleaned hole with isopropyl alcohol and folded pipe cleaner. Inspected threads with borescope and inspection mirror; appeared ok. Discovered that left fitting was now leaking. Consulted with Curt Martin, Dave Pohl, Harry Manvel and VAF members at length.
