Make sure the ground wires are attached to clean and corrosion free bare metal surfaces. Inspect the power wires to the magnets and look for pinched, frayed, or damaged wires and fix as needed. Make sure the brakes are properly adjusted (there should be a slight but constant drag of the pads on the drums when the wheel is turned). If the truck side checks out fine then it could be the wiring to the brake magnets or the magnets themselves. If it shows power any other time then there is a short somewhere between the connector and the brake controller you will need to track down. You can test the brake output pin and it should only show power with the manual override. Make sure the truck and the trailer side connectors are clean and free of corrosion inside and out. Many times, dirt or corrosion can cause a short in a trailer connector. Hi George - here are a few things to take a look at: Now that you know how an Electric Brake works, go ahead and find the part you need from the trailer brake assembly OTHER TRAILER ELECTRIC BRAKE RESOURCES What Are Electric Brakes? ![]() The brake control then sends a current back to the trailer to activate the brakes. ![]() When the driver steps on the brakes it sends a current to the brake control in the vehicle. There are electrical wires running from the trailer connector back to each brake on the axle, as well as to the trailer lights, to create a complete circuit. How does the electricity get to the trailer brakes? Where does it come from? How do we know which brake to use? Here's how it works: An electrical connection on the trailer plugs into the connector on the vehicle. When the shoes press against the inside of the drum, they prevent the hub, and consequently the wheel that's touching the ground from spinning. Those shoes have a special brake pad material on them that resists the heat caused by that friction. When it contacts this area, the friction causes it to rotate, which moves the actuating arm, and pushes the shoes out against the drum. The magnet is attracted to the drum face. When electricity is on, it magnetizes the brake magnet. How does electricity make this brake work? The magnet in the backing plate has 2 conductor wires which tap directly into the trailer wiring. ![]() The 4 smaller holes represent bolt holes which are used to bolt the backing plate onto the Brake Flange which sits behind the spindle. ![]() The large center circle represents the hole through which the trailer spindle goes, so we can install the backing plate on the axle. Take a look at the major parts that make up a brake assembly:
