Replying to Ghetto brake rig

i recently broke a brake off my "binder". There an older binding Rossi Axial 2? no where in my small town (girdwood) has a brake for me out of their parts bin. kind of dreading ordering a new brake online. my question, has anyone ever rigged some leash system and some kind of insert to secure the fit of the boot in the binding. im thinking some cardboard under the heel with a leash connected to my boot? any body have any ideas to buy me some time while i figure out how to get a real brake?
