Electric trailer brakes are a common and reliable way to control your trailer while towing, especially for utility and smaller equipment trailers. They are also economical, but the installation process can be confusing, especially when it comes to the polarity of the brake magnets. The brake magnets in electric trailer brakes 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. However, it is important to ensure that all of the brakes are wired the same way to avoid confusion in case of an electric brake failure.

What You'll Learn
Electric trailer brake magnets are non-polarized
The magnets work like a common resistor. One wire is attached to the power and one is attached to the ground wire. It is recommended to run a common ground wire from the plug to the magnets. The brakes should be wired in parallel, not in series.
When installing an electric brake assembly, it is important to make sure that all of the brakes are wired the same. This means that all of the wires of one colour should be common to either the hot wire or the ground. For example, if your brakes have a blue and a black wire, then all of the blue wires should be connected to the hot wire, and all of the black wires should be connected to the ground.
The main thing to remember when wiring trailer brakes is to ensure that the wires are not crossed. This is why it is often easier to have two different-coloured wires, as it makes it easier to keep them straight. However, as mentioned, the colour of the wires does not matter in terms of polarity, as the magnets are non-polarized.

The wires of brake assemblies are polarity-sensitive
The wires of brake assemblies are not polarity-sensitive. Trailer 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 have the same wire colour for both leads.
When installing an electric brake assembly, either wire can be used for the brake signal and the ground wire. It is recommended to run a common ground wire from the plug to the magnets. The brakes should be wired in parallel, not in series.
It is important to note that the magnets themselves do not have polarity, but each must have a ground wire and a hot wire to complete the circuit powered by the brake controller. That is why they typically have two wires of the same colour.
When rewiring, it is important to ensure that all brakes are wired the same. For example, if your brakes have a blue and a black wire, then all blues should be common to either the hot wire or the ground, and all blacks should be common to the opposite.

Electric brakes are a common and reliable means to control trailers
The electric braking system uses an electromagnet to activate the brake pads. This system does not have polarity, meaning that either wire can be used for the brake signal or as the ground wire. This flexibility simplifies the installation and maintenance process.
However, electric brakes are prone to wear and tear over time. Constant movement and exposure to road debris can lead to faults, malfunctions, and the need for replacements. This is especially true for trailers used extensively or in demanding conditions, where traditional electric brakes may wear out quickly and lead to Department of Transportation (DOT) violations.
To address these issues, electric-over-hydraulic brakes have been introduced. This hybrid system combines the control of electric braking systems with the superior stopping power of hydraulic brakes, providing a more robust and reliable solution for heavy-duty or frequent use.
In conclusion, electric brakes are a widely-used and dependable option for trailer control, offering precise performance and ease of maintenance. However, for trailers subjected to rigorous use, electric-over-hydraulic brakes may be a more suitable choice to ensure optimal reliability and safety.

Electric drum brake magnets are non-polarized
Electric trailer brakes are a common and reliable way to control your trailer while towing. They are most often used on utility and smaller equipment trailers. When it comes to repairing or replacing them, the parts most often replaced are the shoes and magnets. These parts wear out over time and should be inspected periodically and replaced when necessary.
The 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 colour for both leads. When installing an electric brake assembly, either wire can be used for the brake signal and the ground wire, it will not matter which wire is used for which.
For example, on the Harbor Freight 4x8 folding trailer, the magnet wires are not polarized, so either wire can be attached to the frame as ground or used for the +12V brake circuit. Similarly, on trailer brake magnets like the #23-106, the magnets are not polarity-sensitive, so either wire can be used as the power or ground as long as the other is the opposite.
It is important to note that while the magnets themselves do not have polarity, they require a ground wire and a hot wire to complete the circuit powered by the brake controller. This is why it is recommended to run a common ground wire from the plug to the magnets, and the brakes should be wired in parallel, not in series.

Brake magnets are direct current devices
Electric trailer brakes are a common and reliable means to control your trailer while towing. They are most often used on utility and smaller equipment trailers. The parts that often need to be replaced are the shoes and magnets. They wear from use and should be inspected periodically and replaced when needed.
Brake magnets are direct current (DC) devices. They require positive 12-volts and negative 12-volts (ground connection) to become activated. The magnets themselves do not have polarity, but each must have a ground wire and a hot wire to complete the circuit. That's why they typically have two wires of the same colour. Either wire can be attached to either segment of the circuit. It is recommended to run a common ground wire from the plug to the magnets. The brakes should be wired in parallel, not in series.
When installing an electric brake assembly, either wire can be used for the brake signal and the ground wire. It will not matter which wire is used for which. However, it is important to make sure that all of the brakes are wired the same. For example, if your brakes have a blue and a black wire, then all of the blues should be common to either the hot wire or the ground, and all of the blacks should be common to the opposite.
It is also important to note that if you need to replace a magnet, it is advisable to keep the magnets on each end of the same axle the same age. So, if you must replace one, replace the opposite side as well. Additionally, be sure to use the same size and brand of magnet as the one being replaced.
