Finally got around to servicing the brakes with brake fluid. I had originally tried this a few weeks ago, but for some reason the brake assembly seemed clogged and the fluid wouldn't pump through it (but it did pump out onto my garage floor no problem!!). Matco to the rescue: A little high pressure air through the bleeder assembly cleared things out and now the brake lines and resevoirs are filled.
Filled brake line down the back of the right main gear to the brake assembly.
Brake lines running forward through the parking brake to the pilot side brake pedals.
