Converting your trailer’s air brakes to electric brakes can provide more precise control, easier maintenance, and overall improved performance, especially for trailers that require long-distance towing. Air to electric trailer brake conversion kits offer a straightforward solution for making this transition, allowing you to upgrade your trailer’s braking system without extensive modifications. In this comprehensive guide, we will explore everything you need to know about air to electric trailer brake conversion kits, from how they work to the benefits they offer and the step-by-step conversion process.
Why Convert from Air to Electric Trailer Brakes?
There are several reasons why trailer owners might choose to convert their air brakes to electric brakes:
- Precision and Control: Electric brakes provide more precise braking control than air brakes, which can be especially useful when towing trailers over long distances or through varied terrain.
- Easier Maintenance: Electric trailer brakes are generally easier and less expensive to maintain compared to air brake systems, which can involve more complex components and repairs.
- Compatibility with Tow Vehicles: Many modern towing vehicles are equipped with electric brake controllers, making electric trailer brakes more compatible and easier to use.
- Improved Safety: Electric brakes offer proportional braking, meaning the brakes engage smoothly in relation to the braking force applied by the towing vehicle, reducing the risk of trailer sway or jackknifing.
How Do Air to Electric Trailer Brake Conversion Kits Work?
Air to electric trailer brake conversion kits are designed to replace your trailer’s air brake system with electric brakes. These kits typically include the necessary components to retrofit your trailer, including:
- Electric Brake Assemblies: These replace the air brake components on each wheel, providing electric control over braking.
- Electric Brake Controller: This is installed in the towing vehicle to control the electric brakes based on the driver’s brake input.
- Wiring and Connectors: These allow the electric brake system to connect to the towing vehicle’s brake controller.
The conversion process involves removing the air brake components, installing the new electric brake assemblies, and connecting the system to the electric brake controller in the towing vehicle. Once installed, the electric brakes function by receiving a signal from the brake controller when the driver applies the brakes. This signal activates the trailer’s electric brakes, allowing for smooth and controlled stops.
Step-by-Step Guide to Converting Air to Electric Trailer Brakes
Converting your trailer from air brakes to electric brakes can be a detailed process, but with the right conversion kit and a systematic approach, you can successfully upgrade your trailer’s braking system. Here’s a step-by-step guide:
1. Gather the Necessary Tools and Equipment
Before starting the conversion, make sure you have all the necessary tools, including a socket set, screwdrivers, wire cutters, and electrical tape. Additionally, ensure you have purchased a complete air to electric trailer brake conversion kit that is compatible with your trailer.
2. Remove the Air Brake Components
Begin by safely raising and securing the trailer on jack stands. Remove the wheels to access the brake assemblies. Disconnect and remove the air brake components, including the air lines, brake drums, and air chambers.
3. Install the Electric Brake Assemblies
Once the air brake components have been removed, install the electric brake assemblies in their place. Follow the manufacturer’s instructions to ensure proper installation. This will typically involve bolting the new brake assemblies onto the trailer’s axle and connecting the brake shoes to the drums.
4. Connect the Wiring
Next, connect the wiring for the electric brakes. Run the wiring from the brake assemblies to the trailer’s wiring harness, making sure to secure the wires to prevent them from coming loose while towing. The wiring should connect to the towing vehicle’s brake controller, which sends the signal to activate the trailer brakes.
5. Install the Brake Controller
If your towing vehicle doesn’t already have an electric brake controller, you will need to install one. This device will be mounted inside the vehicle and connected to the trailer’s wiring via the towing connector. The brake controller allows the driver to adjust the braking force based on the trailer’s weight and road conditions.
6. Test the Brakes
After the installation is complete, test the brakes by driving the trailer at low speeds in a controlled environment. Apply the brakes gradually to ensure they engage smoothly and proportionally. Adjust the brake controller settings as needed to achieve the desired level of braking force.
Benefits of Converting to Electric Trailer Brakes
Converting from air brakes to electric brakes offers numerous benefits:
- Improved Braking Control: Electric brakes provide smoother and more proportional braking, allowing for safer stops, especially with heavy loads.
- Lower Maintenance Costs: Electric brakes are simpler to maintain, with fewer moving parts compared to air brake systems, reducing overall maintenance costs.
- Increased Compatibility: Most modern towing vehicles are equipped with electric brake controllers, making electric brakes a more compatible option for a wide range of trailers.
Maintenance Tips for Electric Trailer Brakes
Once your trailer has been converted to electric brakes, regular maintenance is essential to keep the system functioning properly:
- Check Wiring Connections: Regularly inspect the wiring connections for any signs of wear or corrosion. Ensure that all connections are secure and free of damage.
- Inspect Brake Components: Periodically inspect the brake shoes, drums, and magnets for wear or damage. Replace worn components to maintain optimal braking performance.
- Test Brake Controller Settings: Before each trip, test the brake controller settings to ensure that the brakes are engaging as expected and that the trailer stops smoothly.
Conclusion
Upgrading your trailer’s air brakes to electric brakes using a conversion kit can provide significant benefits in terms of control, safety, and maintenance. With the right tools and components, the conversion process is straightforward and can offer long-term advantages for those who tow heavy loads or travel long distances. By following the steps outlined in this guide and maintaining your new electric brake system regularly, you’ll be ready for safer and more reliable towing.
