How does the magnet work on electric brakes?
When electricity is on, it magnetizes the brake magnet. The magnet is attracted to the drum face. When it contacts this area, the friction causes it to rotate, which moves the actuating arm, and pushes the shoes out against the drum.
How long do electric trailer brakes last?
A good safety rule is to check your brakes every time you head out, and certainly to replace them no less often than you replace your tires. I suggest no more than 12 months or 12,000 miles between changing brake parts that can wear.
Do electric trailer brakes work without a controller?
Electric trailer brakes do not work without a brake controller. If your trailer is equipped with electric brakes, you will need a brake controller to tow. However, some trailers are equipped with surge brakes. These are a hydraulic braking system that uses the trailer’s own weight and momentum to actuate the brakes.
What causes electric trailer brakes to stop working?
Common causes of this condition are; poor electrical connections, open circuits, insufficient wire size, broken wires, blown fuses (fusing of brakes is not recommended), improperly functioning controllers or resistors. Another common electrical problem is shorted or partially shorted circuits (indicated by abnormally high system amperage).
Why does my brake controller not work when I press the brake?
It connects to the wire on this switch that carries a signal ONLY when the brake pedal is pressed. It should not have a signal at any other time. Use a circuit tester, like # 40376, to test the wires. If your brake controller red wire is not connected to the correct wire, or is loose or broken, this would cause the problem you are experiencing.
How do you check electric brakes on a trailer?
The controller of a trailer’s electrical brake system is a device that feeds the current to your electric brakes. When the brake pedal in your tow vehicle is being pressed, the electromagnets in the brakes themselves get activated and your trailer stops. This magnetic action of the brake controller could be checked in the following ways: 1.
Where does the red wire for the brake controller go?
The red wire needs to attach to the stop light switch above the brake pedal. It connects to the wire on this switch that carries a signal ONLY when the brake pedal is pressed.

What to do if your brakes are not working?
If the problem still persists after checking each brake assembly you will want to work your way up the wiring from the trailer to the brake controller. Begin by inspecting the wires from the brake assembly up to the trailer connector for any cut or frayed wires.
