Did a little more work to the brakes. Caliper is just balsa glued to a styrene support that attaches to the axle. The styrene itself doesn't really provide enough attachment to the axle so a balsa or ply packing will be added behind the support which should be sufficiently hidden from view. After looking at the setup it appears that the rotor is a little to "wide" so the inner portion will be trimmed down a bit (if that makes sense).
