Chaining axle to frame?

[path1]

Doing some research on brakes. Saw this pic in old posting. Never seen that before. I assume in event of broken spring or axle or U bolts?

My guess would be it has nothing to do with the brake wire, but rather to help in tire changing. The chain would prevent the wheel from dropping down when jacking up the frame. The tying of the wires to the chain might just be to keep them from being pinched between the axle and rubber bumper stop.

Properly routes wires do not need anything more than enough slack to move up and down. Mine have been out in he open for near 20k miles with no issues.

No need to over complicate things.

After reading your link... it appears to be someones's idea of how to control/protect the wires going to the brakes.
I have chains that I attach to my rear axle when I pick up the back of my toad so the axle/tires do not drop down. Click on "How I tow" below.

:h What was he thinking? It would limit spring travel and lead to early brake failure when the wires get torn off.

Looks like chain is to limit downward movement (unloaded) to prevent brake wires from being pulled/broken
