I decided that I'd like to have differential toe brakes instead of the Sonex standard brake hand lever. Another Sonex builder came up with a design and offered to product a bunch of them.
The brakes seem like they will work well. I had took the two brake levers to work, and was able to have the welding touched up, and then powder coated.
I don't have any pictures of the brake bleeding process, but it went fairly well. The brake lines have a little air in them, but the pedals feel firm.
