What are electric brakes and how do they work on a trailer?
Electric brakes are a type of braking system used on trailers that rely on an electrical signal to activate the brake mechanism. When a driver presses the brake pedal in the towing vehicle, a signal is sent to the trailer’s brake controller, which then sends an electrical current to the brake assembly on the trailer. This current engages the brakes, allowing them to slow down the trailer effectively.
The main advantage of electric brakes is that they provide more consistent and reliable stopping power compared to traditional surge brakes. Additionally, electric brakes can be controlled via an adjustable brake controller, which allows the driver to fine-tune the braking force to suit different loads and road conditions. This makes them a popular choice among those who frequently tow heavier trailers.
