Question:

Are the brake magnets polarity sensitive

asked by: Gary

Expert Reply:

You asked a good question. No, electric drum brake magnets are non-polarized, meaning that either of the two leads can be used for grounding to the trailer frame or for connection to the trailer brake controller circuit. This is why brake assemblies and replacement magnets have the same wire color for both leads.

You'll want to use 10-gauge wiring for connecting the brake assemblies to the trailer's brake circuit.
We offer part # 10-1-1 which is sold by the foot.
