Understanding Trailer Brake Systems
Trailer brake systems are crucial for safe towing, as the tow vehicle alone often lacks sufficient stopping power to manage the combined weight. These systems work by applying braking force directly to the trailer’s wheels, assisting the tow vehicle in decelerating and maintaining control.
There are several types of trailer brake systems, including electric, electric-over-hydraulic (EOH), and surge brakes. Each operates differently, but the core principle remains the same: to provide supplemental braking. Understanding your trailer’s specific brake system is essential for selecting the correct Tekonsha controller.
A properly functioning trailer brake system distributes the braking load, reducing stress on the tow vehicle’s brakes and improving overall stability. Regular inspection and maintenance of both the trailer brakes and the Tekonsha controller are vital for optimal performance and safety on the road.
Electric Trailer Brakes: How They Work
Electric trailer brakes utilize electromagnets within each wheel hub to create braking force. When the driver applies the brakes in the tow vehicle, a signal is sent to the Tekonsha brake controller. This controller converts the signal and sends DC power to the trailer brakes.
The electrical current energizes the electromagnets, which pull against a rotating drum or rotor attached to the wheel. This creates friction, slowing and stopping the trailer. The amount of current – and therefore braking force – is proportional to the signal from the tow vehicle, allowing for controlled deceleration.
Electric brakes are commonly found on travel trailers, utility trailers, and many other types of towed vehicles. They are relatively simple, reliable, and offer good stopping power when properly adjusted and maintained. A Tekonsha controller is essential for managing these systems effectively.
Electric-Over-Hydraulic (EOH) Trailer Brakes
Electric-Over-Hydraulic (EOH) brakes represent a more sophisticated braking system, commonly used with larger, heavier trailers – like those for horses or heavy equipment. Unlike standard electric brakes, EOH systems don’t directly apply braking force with electromagnets.
Instead, the Tekonsha controller sends an electrical signal to a hydraulic pump unit on the trailer. This pump pressurizes hydraulic lines, which then activate the trailer’s brake calipers, similar to the braking system in most modern vehicles. The intensity of the electrical signal dictates the hydraulic pressure, and thus, the braking force.
EOH systems offer superior stopping power and control compared to electric brakes, particularly for substantial loads. They require a Tekonsha controller specifically designed to support EOH functionality for optimal performance and safety.
Surge Brakes vs. Electric Brakes
Understanding the differences between surge and electric trailer brakes is crucial for selecting the right Tekonsha controller and ensuring optimal braking performance. Surge brakes, typically found on boat trailers, operate mechanically. When the tow vehicle slows down, the trailer’s momentum pushes it forward, activating a master cylinder within the trailer’s tongue.
This master cylinder applies hydraulic pressure to the trailer’s brakes. Electric brakes, conversely, rely on an electrical signal from the Tekonsha controller to activate electromagnets within the brake drums or rotors. The controller’s signal intensity determines braking force.
Tekonsha controllers are generally not compatible with surge brakes, as they don’t interface with the mechanical activation system. Electric brakes offer more adjustability and control, while surge brakes are simpler and require less maintenance.
