Had tiny leak in brake fitting on right brake. Had to remove, clean threads and chase threads with tap to get fitting to seat where I could re-attach brake line. By carefully removing brake line with parking brake set and controlling bleed valve, I was able to accomplish all without having to do a full brake line bleed. In process, I had to cut the safety wire and remove the brake assembly to do my repair. All went back into place and pressure test with parking brake to hold pressure showed no leaks. Brake bolts re-installed and re-safety wired. Safety wire went real quick this time....less than 5-10 minutes instead of 1/2 hour or more last time.
