Narrative:
Installed brake for number-3 wheel incorrectly. First time doing a brake; didn't know that I could switch fittings with safety wire to other end of brake. Plane did not fly. Went back out with inspector to correct the mistake. [Recommend] providing more training and make sure someone is there to help out with first time installs.
