When towing heavy loads, having precise and reliable braking control is crucial. One of the most advanced systems available is the electric over hydraulic trailer brake controller. This system combines the benefits of both electric and hydraulic brakes, providing superior stopping power and smoother braking. In this article, we’ll explore how electric over hydraulic brake controllers work, their benefits, and what to consider when choosing one for your trailer.
What Is an Electric Over Hydraulic Trailer Brake Controller?
An electric over hydraulic (EOH) brake controller is a device installed in your towing vehicle that controls the trailer’s braking system. Unlike traditional electric brakes, which use electromagnetic force to engage brake shoes, EOH systems use an electric signal to control a hydraulic actuator. This actuator then applies hydraulic pressure to the trailer’s brake calipers or drums, providing the braking force.
How Does an Electric Over Hydraulic Brake Controller Work?
The operation of an electric over hydraulic brake controller involves several key components:
- Brake Controller:
- Installed in the towing vehicle, the brake controller sends an electric signal when the vehicle’s brakes are applied. This signal is proportional to the pressure applied to the vehicle’s brakes, ensuring smooth and controlled braking.
- Hydraulic Actuator:
- The electric signal from the controller activates a hydraulic actuator mounted on the trailer. This actuator pressurizes the hydraulic fluid, which is then sent to the trailer’s brake calipers or drums.
- Brake Calipers or Drums:
- The hydraulic pressure forces the brake pads or shoes against the rotors or drums, creating friction and slowing down the trailer. The strength of this braking force is controlled by the brake controller.
Benefits of Electric Over Hydraulic Brake Controllers
Choosing an electric over hydraulic brake controller offers several advantages:
- Superior Braking Power:
- EOH systems provide stronger and more consistent braking power, making them ideal for heavy trailers or situations where precise control is essential.
- Smoother Braking:
- The proportional braking control ensures that the trailer’s brakes engage smoothly, reducing the risk of jerky stops and improving overall safety.
- Better Heat Management:
- Hydraulic systems are better at managing heat generated during braking, reducing the risk of brake fade on long descents.
- Increased Durability:
- Hydraulic components are generally more durable than purely electric systems, requiring less frequent maintenance and offering a longer lifespan.
Factors to Consider When Choosing an Electric Over Hydraulic Brake Controller
When selecting an EOH brake controller, consider the following factors:
- Compatibility:
- Ensure the brake controller is compatible with your towing vehicle and the trailer’s hydraulic brake system. Check the voltage requirements and the number of axles it can control.
- Ease of Installation:
- Look for a controller that is easy to install, especially if you plan to do it yourself. Some models offer plug-and-play installation, simplifying the process.
- Adjustability:
- The ability to fine-tune the braking force is crucial, especially if you tow different loads. Choose a controller with easy-to-use adjustment settings.
- Display and Interface:
- A clear display that shows the braking force and other important information is helpful for monitoring the system while driving.
- Price:
- While more expensive models offer advanced features, you should choose a controller that fits your budget and meets your towing needs.
Maintaining Your Electric Over Hydraulic Brake System
Proper maintenance is essential to ensure the longevity and performance of your EOH brake system:
- Regular Inspections:
- Regularly check the hydraulic fluid levels and inspect the brake lines for leaks or damage.
- Test the Brake Controller:
- Periodically test the brake controller to ensure it’s functioning correctly and providing the appropriate amount of braking force.
- Replace Worn Components:
- Keep an eye on the brake pads or shoes, and replace them as needed to maintain optimal performance.
Conclusion
An electric over hydraulic trailer brake controller offers unmatched braking power and control, making it an excellent choice for those who tow heavy or valuable loads. By understanding how these systems work and considering the key factors when choosing a controller, you can ensure a safe and smooth towing experience. Regular maintenance will keep your braking system in top shape, providing peace of mind on every journey.
