Do Trailer Axles Have to Face Certain Direction

Published 04/17/2019

Question:

I have a tandem cargo trailer with no brakes. I want to install and wire one axle to a new brake axle. Does it matter which way the wires face on the axle itself? Or is there any way I might install the axle backwards to where the brakes may not work or be faulty? I appreciate your help.

I attached a diagram that shows how tandem axle trailer brakes get wired up. What's great is that for trailer brake magnets either wire can be used as the power or ground wire.

The second picture I attached show which direction brake assemblies need to install to work to their potential. They are directional and if you install them backwards they won't work we as well.
