Brake Magnet Wire Color

This is a question relating to the 'power' delivered by electric brake magnet.

There is a lack of information on the internet or elsewhere about the strength of brake magnets. After discussions with the technical experts at RV /trailer parts suppliers I have had responses that range from 'they're the same ' ' they're different', ' manufacturers use what wire is on hand', etc.

My question relates to my Jayco 5th wheel(GVWR 11,300 lbs.) which uses 5.2K axles and the magnet has white wires. I wish to improve braking on the unit by upgrading to 7K assemblies some of which use a white wire magnet while others use black wire magnets.

Can anyone share any experience you may have had with this or lead me to a credible source of information as to the relative strength of brake magnets by color of the electrical leads to the unit.

I have tried looking at / for government sources but have come up empty.

thanks
  • Doesn't matter. The magnet is a coil. Power goes in one side and out the other.
    That's all.

    B.O.
  • I just checked, my old 7,000 brakes have white wires. The new ones have white.

    Call Dexter axle and talk to a tech. They are very helpful whenever I have called. I am not sure if wire colors are different but I do believe there are different strength magnets.
  • The wires are interchangeable. Color isn't important. The best thing you can do is get self-adjusting brakes to replace the manual adjustment. The power is determined by the current supplied to it.
