Hi again Larry,
That flex line looks way too long to me, but I am not working with Toyota calipers and they might require something different than I'm used to.
You can reposition those flex lines a bit by bending the mounting tab on the frame. Also, you can often loosen the fitting and repostion/retighten so that they bend a specific direction. I'm not sure if that's enough to resolve the problem here, though.
Hoepfully, someone else who is using Toyota calipers will jump in here.
