What are electric trailer brakes and how do they work?
Electric trailer brakes use an electric current to apply braking action, providing a way to stop the trailer in tandem with the towing vehicle. They consist of a controller in the tow vehicle that sends a signal to an electric brake assembly mounted on the trailer wheels. When the tow vehicle applies the brakes, the controller activates the electric brakes proportionally, allowing for smoother stopping and reducing wear on the main vehicle’s brakes.
The braking force is adjustable, depending on the weight of the trailer and the load it carries. Electric brakes work by activating an electromagnetic coil that pulls a lever, engaging the brake shoes against the drum. This eliminates the reliance on hydraulic systems, making it simpler to set up and ensuring a more reliable braking experience.
What are the advantages of using electric brakes over hydraulic brakes?
One significant advantage of electric brakes is that they provide quicker response times. When the driver applies the brakes in the towing vehicle, the electric brake system responds almost immediately, meaning the trailer can come to a stop faster. Additionally, the ability to adjust the braking force on the fly allows for better control, especially when dealing with varying loads and driving conditions.
Another benefit is their enhanced reliability and reduced maintenance needs. Electric brakes don’t rely on hydraulic fluid, which can leak or require regular checks. Instead, they function through a simple electrical connection, which minimizes parts that can fail and reduces overall repair costs over time.
