Has any one had a brake system just for no unknown reason start looseing air pressure, for almost 45 days the air system held air pressure no loose at all after 10 great flight here in Alaska the Brake system started to bleed down over a 10 hours it will bleed 100 PSI off. It is no real big deal it hold air for a normal flight. I have safity wire all connection with 020 ss wire.

Anyone seen this happen and were you able to fix it.??????
