Had a drip, then a leak from the pilot master brake cylinder (Left) at the 90 deg fitting pipe threads. Removed all the fittings and added a small ring of thread seal (Permatex) on the pipe threads and retorqued.
Need to finish by re-bleeding the brakes.
UPDATE - done 5.14.17 and did a taxi test of the brakes, and other changes in the last week. Prepared to fly Phase 1 again. (Left brake dragging a bit, and need follow-up)
