Electric over hydraulic brakes combines the control of electric braking systems with the power of hydraulic brakes
Electric over hydraulic brakes are a hybrid braking system that combines the control of an electric braking system with the power of hydraulic brakes. This combination offers several advantages over traditional electric brakes, particularly for heavy-duty applications such as hotshot trucking and heavy trailers.
Electric over hydraulic brakes provide superior stopping power compared to standard electric brakes. This is due to the use of hydraulic brake fluid, similar to that found in cars, which enhances the overall braking efficiency. The system can deliver a stronger braking force, making it ideal for heavy loads and trailers. The braking force is proportionally controlled, ensuring balanced braking between the tow vehicle and the trailer. This prevents issues such as unequal braking, increased risk of jackknifing, and trailer sway, ultimately enhancing overall driving safety.
One of the primary benefits of electric over hydraulic brakes is the reduction in electrical connections at the hubs, minimising potential issues caused by debris and corrosion. The electrical connections stop at the brake booster, reducing the risk of electrical faults, which are common in traditional electric brakes due to constant movement and road debris. This makes electric over hydraulic brakes more reliable and robust, especially for applications that require extensive and frequent use.
While electric over hydraulic brakes have a higher upfront cost, they offer long-term savings due to reduced maintenance costs. The system is also built to handle heavy weather conditions and performs well in demanding situations. Manufacturers recommend using electric over hydraulic brakes for boats or trailers exceeding 3,500 pounds to ensure safe and effective braking performance.
In summary, electric over hydraulic brakes offer a robust and reliable solution for heavy-duty applications. By combining the control of electric systems with the power of hydraulic brakes, this braking system provides superior stopping power, enhanced safety, and reduced maintenance concerns, making it a preferred choice for many customers with demanding towing requirements.

This system is ideal for trailers used in demanding conditions
Electric over hydraulic brakes are a hybrid braking system that combines the control of electric braking systems with the stopping power of hydraulic brakes. This makes them ideal for trailers used in demanding conditions.
Electric over hydraulic brakes are activated when the tow vehicle brakes are applied, and the trailer surges forward. The system then sends an electric signal to the trailer's brake system, which uses this signal to control a hydraulic actuator on the trailer. This actuator is essentially an electrically powered hydraulic pump, which converts the electric signal into hydraulic pressure to apply the brakes on the trailer.
This setup provides superior stopping power, making it perfect for trailers used in challenging environments. The system is also compatible with various trailer types, including utility, boat, livestock, horse, and 5th Wheel RVs. Additionally, it improves overall towing safety by reducing the risk of trailer sway and enabling more effective braking.
One of the primary benefits of electric over hydraulic brakes is the significant reduction in electrical connections at the hubs, minimising potential issues caused by debris and corrosion. This makes them a robust option for trailers that cover extensive miles regularly, as constant movement and road debris can wear down electrical connections, leading to faults and the need for replacements.
While electric over hydraulic brakes may be more expensive upfront, they can offer substantial long-term savings due to reduced maintenance costs. This makes them a cost-effective choice for trailers used in demanding conditions, as they can withstand constant commercial use without wearing out quickly.

Electric over hydraulic brakes are more expensive upfront but offer long-term savings
Electric over hydraulic brakes are a combination of the control of electric braking systems and the stopping power of hydraulic brakes. They are activated when the tow vehicle brakes are applied, and the trailer moves forward. The electric over hydraulic (EOH) actuator is electric, which means the brakes are applied instantly, with almost no lag time.
While electric over hydraulic brakes are more expensive upfront, they offer long-term savings. For example, upgrading from a 10,000-pound electric brake axle to an electric over hydraulic system might cost around $1,600 more. However, this difference can be negligible when considering the reduced maintenance costs. The Dexter electric over hydraulic disc brake axle, for instance, has a 12,000-pound capacity and features visible calipers and easily inspectable brake pads. The superior stopping power and ease of maintenance make it a worthy investment for those using their trailers extensively.
The electric over hydraulic system has fewer electrical connections at the hubs, minimising issues caused by debris and corrosion. The electrical connections stop at the brake booster, reducing the risk of electrical faults. This system also uses hydraulic brake fluid, enhancing the overall braking efficiency. The truck sends a signal to the brake booster, which then activates the brake pump to stop the trailer. The calipers and brake pads are easy to inspect and replace, and bleeding the system is simple if air gets into the lines.
The Deutsche Hydrapro EOH brake actuator is another example of an electric over hydraulic system that offers superior performance. It provides a smooth brake application, maintains higher pressure with less amperage, and enhances driver confidence. It also features a bigger, more efficient motor, and a separate hydraulic fluid reservoir to prevent leaks.

Electric over hydraulic brakes are an option for various trailer types, including utility, boat, and RVs. They are also compatible with livestock, horse, and 5th Wheel RVs trailers. These braking systems are designed to control the application of hydraulic brakes using an electric signal, providing better control and responsiveness. They are especially useful for trailers that frequently operate in challenging environments or cover long distances, as they offer superior stopping power and minimise the chances of electrical faults at the hubs.
The electric over hydraulic brake system is activated when the tow vehicle brakes are applied, with the trailer surging forward. The electric signal from the controller in the towing vehicle is sent to the electric over hydraulic brake actuator, which is essentially an electrically powered hydraulic pump. This actuator then converts the electric signal into hydraulic pressure, activating the trailer's brakes with minimal lag time.
The compatibility of electric over hydraulic brakes with various trailer types enhances safety during towing. By reducing the risk of trailer sway and improving braking effectiveness, these brake systems are particularly well-suited for larger trailers and heavy loads. Additionally, the adjustability of these systems allows for customisation according to different towing conditions and user preferences.
The versatility of electric over hydraulic brakes makes them a robust option for a diverse range of trailers. While they may have a higher upfront cost compared to traditional electric brakes, the long-term savings in maintenance and replacement costs can be significant.
