Just a note on safety wiring (coming from an aviation background);
Taken from "Acceptable Methods, Techniques and Standards"
The word safetying is a term universally used in the aircraft industry. Briefly, safetying is defined as: “Securing by various means any nut, bolt, turnbuckle etc., on the aircraft so that vibration will not cause it to loosen during operation.” These practices are not a means of obtaining or maintaining torque, rather a safety device to prevent the disengagement of screws, nuts, bolts, snap rings, oil caps, drain cocks, valves, and parts.
Therefore it should attach in a manner that will pull the fastner in tightening manner.
Personally i don't see the 2 fasteners tightening upon one another in the initial picture. The brake shear bolts could essentially loosen, thereby creating a danger (just my 2 cents).
As for safety wiring the tails of hose clamps, i have tested and tried that and have proven to myself and others that it is completely ineffective. It is very easy to loosen the worm screw portion of the clamp (screw head) rendering the sealing of the hose ineffective.
