Every trailer owner knows that when connecting a trailer, the brakes are the most important thing. Brakes help maintain control through stopping power, especially in hazardous road situations. Without trailer brakes, the vehicle’s brakes would be strained as heavy loads push against them, leading to longer stopping distances. Once a trailer exceeds a certain weight, it is legally required to have brakes. That is why it is important to understand how brake systems work so you can choose the best option for your needs.
Kinema Trailer Depot offers premium trailers in Douglas, GA, equipped with the latest brake systems. Learn about electric brakes vs. surge brakes with us.
Electric Trailer Brakes
Best suited for heavier trailers, electric brakes are the most common system used today. With a brake controller mounted in the cab, the brake systems are powered by the vehicle’s electrical system.
How electric trailer brakes work?
- The driver presses the brake pedal.
- A controller sends the signal to the trailer’s brakes.
- Electromagnets inside the drums are activated.
- The action creates friction.
- The trailer slows down in proportion to how firmly the tow vehicle is braking.
Strengths and Advantages of Electric Brakes
- One of the biggest strengths of electric brakes is adjustability.
- Fine-tune braking strength for different loads, road types, and weather conditions
- Popular with RVs, equipment haulers, and utility trailers
- Smoother stops and reduced jerking
- Improved confidence behind the wheel
Surge Trailer Brakes
Also known as hydraulic brakes, these have a very different mechanism. Surge brakes rely on a hydraulic actuator. This is built into the trailer’s tongue.
How surge trailer brakes work?
- The tow vehicle slows down.
- The trailer’s forward momentum compresses the actuator.
- Brake fluid is forced into the lines.
- The trailer’s brakes are applied.
Surge systems can be challenging because drivers cannot manually adjust, apply brakes, or reverse on steep hills.
Electric brakes vs surge brakes
| Electric Brakes | Surge Brakes |
| Responsive | Reactive |
| Braking force in harmony with tow vehicle | Only engages when trailer pushes forward |
| Good even in demanding conditions | Cannot perform well in demanding conditions |
| Replacement parts widely available | Brake lines wear out and leak |
| Systems easy to repair | Hydraulic systems are complicated |
| Carry heavier loads such as equipment haulers | Only used for small and mid-sized trailers |
Legal Requirements
Trailers above a certain weight must be equipped with brakes. Electric brakes meet the requirements for heavier loads such as RVs, equipment haulers, and more. These demand electric brakes for safety compliance. Surge brakes are for smaller vehicles, rental fleets, and trailers that are pulled by different vehicles. It is, however, important to match your brake system to your trailer’s weight, type, and use so that you comply with safety regulations and the law.
Working in the real world
Consider, for instance, a family towing a huge camper across various states. They can adjust braking strength instantly if they are using electric brakes. They can also apply the trailer brakes separately when descending steep grades. Additionally, they can fine-tune performance to changing road conditions. Electric brakes provide control, and long-distance travel becomes less stressful. They thrive in demanding conditions.
The right braking system
Don’t debate whether an electric system vs surge system is better. Instead, consider which brake system is best for you. Are you looking for the adjustability, precision, and control of electric brake systems? Do you need indispensable heavy-duty hauling and long-distance towing? Or are you looking for self-containment and simplicity, and a brake system for light trailers and casual users? Match the brake system to your towing habits and your driving environment.
