For anyone towing heavier trailers, ensuring that your braking system is reliable and effective is essential for safe towing. One of the best solutions for trailers carrying significant loads is a 12 inch electric trailer brake kit. These kits come equipped with everything you need to upgrade or install new brakes on your trailer, providing powerful stopping capabilities and peace of mind on the road. In this guide, we’ll cover everything you need to know about 12 inch electric trailer brake kits, how they work, the benefits they offer, and tips for installation and maintenance.
What is a 12 Inch Electric Trailer Brake Kit?
A 12 inch electric trailer brake kit is a comprehensive package that includes all the necessary components for installing electric brakes on a trailer. The 12 inch size refers to the diameter of the brake drum, which is larger than standard sizes and is commonly used for heavier trailers such as RVs, car haulers, and equipment trailers. These kits typically include the brake assemblies, drums, and wiring needed for installation, making them a complete solution for anyone looking to improve their trailer’s braking system.
Components of a 12 Inch Electric Trailer Brake Kit
Most 12 inch electric trailer brake kits come with the following essential components:
- Brake Assemblies: These include the backing plate, brake shoes, magnets, and all the hardware needed to engage the brakes.
- Brake Drums: The brake drums work with the brake shoes to create the friction necessary for stopping the trailer.
- Wiring Harness: The kit typically includes the necessary wiring to connect the brake controller in the tow vehicle to the electric brakes on the trailer.
- Mounting Hardware: Nuts, bolts, and other hardware required for securing the brake assemblies to the trailer axle.
Benefits of Using a 12 Inch Electric Trailer Brake Kit
There are several key benefits to choosing a 12 inch electric trailer brake kit for your trailer:
- Increased Stopping Power: The larger brake drums and assemblies offer greater stopping power, which is especially important for trailers carrying heavy loads.
- Complete Kit: A brake kit provides all the necessary parts in one package, ensuring that everything is compatible and ready for installation.
- Improved Safety: With a properly installed 12 inch electric brake system, you’ll have better control over your trailer’s braking, reducing the chances of accidents and ensuring smoother stops.
- Cost-Effective: Purchasing a complete brake kit is often more affordable than buying each component separately, and it simplifies the installation process.
How 12 Inch Electric Trailer Brakes Work
The functionality of 12 inch electric trailer brakes is similar to other electric braking systems. Here’s how it works:
- Brake Controller Activation: When you apply the brakes in your towing vehicle, the brake controller sends an electrical signal to the trailer’s brake system.
- Magnet Engagement: This signal activates magnets inside the brake assemblies, causing them to engage with the brake drums.
- Brake Shoe Engagement: The activated magnets pull the brake shoes outward against the brake drums, creating friction that slows the trailer’s wheels.
- Controlled Braking Power: The brake controller adjusts the braking power based on how much force is applied to the vehicle’s brakes, ensuring that the trailer brakes respond proportionally to the load and driving conditions.
Installation of a 12 Inch Electric Trailer Brake Kit
Installing a 12 inch electric trailer brake kit is a straightforward process if you follow the right steps. Here’s a step-by-step guide to ensure proper installation:
1. Lift and Secure the Trailer
Before you begin, park the trailer on a flat surface, and use a jack to lift the trailer axle off the ground. Ensure the trailer is stable with wheel chocks for safety.
2. Remove the Wheels and Old Brake Components
Take off the wheels and any existing brake components, including the drums, shoes, and magnets. Clean the axle flange and surrounding areas to prepare for the installation of new components.
3. Install the Brake Assemblies
Place the new 12 inch brake assemblies onto the axle flange and secure them with the appropriate bolts. Be sure to follow the manufacturer’s instructions for correct orientation and torque specifications.
4. Connect the Wiring
Run the wiring harness from the brake controller in your vehicle to the trailer. Connect the wires to the brake assemblies, ensuring all connections are secure and free of moisture to prevent corrosion.
5. Install the Brake Drums
Slide the brake drums over the brake assemblies and make sure they fit snugly. The drums should rotate freely when the brakes are not engaged.
6. Test the Brakes
After installation, perform a brake test. Use the brake controller to apply the trailer brakes and ensure that they engage smoothly and effectively.
Maintenance Tips for 12 Inch Electric Trailer Brakes
Proper maintenance is essential to keep your 12 inch electric trailer brakes functioning optimally over time. Here are some tips:
- Regular Inspections: Check the brake shoes, drums, and magnets regularly for signs of wear or damage. Replace any worn parts promptly to maintain effective braking.
- Clean the Components: Keep the brake assemblies clean by removing dirt, rust, and debris that can accumulate and reduce performance.
- Check Wiring Connections: Inspect the wiring for any signs of wear or corrosion and make sure all connections remain secure. Faulty wiring can result in poor brake performance.
- Adjust the Brake Controller: Depending on the load you’re towing, you may need to adjust the settings on your brake controller to provide the appropriate level of braking force.
Conclusion
A 12 inch electric trailer brake kit is an essential upgrade for anyone towing heavy trailers. By providing greater stopping power and improved control, these kits ensure safe and reliable towing, making them ideal for large RVs, car haulers, and commercial trailers. By understanding how these kits work, following proper installation procedures, and maintaining your brakes, you can tow with confidence knowing that your braking system is up to the task.
