With the empennage removed, it was back to the brakes. I temporarily assembled things again and was looking at the locations of everything and the clearances. While looking at the potential routing of the brake lines in the wings, I had an "Aha" moment. Well maybe it wasn't an "Aha" moment, it was more of an "Oh s$%t" moment.

Thinking about the brake line routing made me have a closer look at the brake assembly. With the rudder pedal pushed full travel, I realized the brake master cylinder will be in the way of the landing gear retract torque tube. See attached picture. The torque tube comes out of the hole indicated by the yellow arrow.

I was so busy considering the fitment of the master cylinder to the rudder pedal and its clearances to the seat and the floor, the leverage and travel required to provide sufficient braking power with acceptable foot pressure that I had completely forgotten about the torque tube.

Hmmm. More head scratching required.
