I missed commenting to John earlier. Your visualization of the problem
isn't quite right. With rim brakes, the spokes do not see any braking
forces, since the brakes sit between the spokes and the tire.

The spokes may not see any torque between the hub and rim, but are
certainly forces due to braking that the spokes see.
