Understanding Trailer Electric Brake Controllers

by Emilia Latvala

When it comes to towing a trailer, safety should always be your top priority. One key component that ensures a safe towing experience is the trailer electric brake controller. Whether you're hauling a caravan, boat or any cargo trailer, having a reliable brake controller fitted can make all the difference in providing smooth and controlled stops.

What Are Trailer Electric Brake Controllers?

Trailer electric brake controllers are devices mounted inside your vehicle that manage the electric brakes on your trailer. They work by sending power from the vehicle to the trailer's brakes, allowing them to engage when you hit the brake pedal in your car. This synchronised braking prevents the trailer from pushing or pulling against the vehicle, ensuring a safer driving experience.

Why You Need One

Imagine towing a heavy load down a steep hill without any additional braking support; it's not only daunting but also dangerous. Trailer electric brake controllers help distribute braking force evenly between your vehicle and the trailer. This distribution improves stability and reduces stopping distances, which are crucial factors for preventing accidents on the road.

Moreover, many regions have legal requirements mandating brake controllers for trailers over a specific weight. Therefore, having an electric brake controller isn't just about safety, it's also about compliance with legal standards.

Types of Brake Controllers

There are mainly two types of trailer electric brake controllers: time-delayed and proportional.

Time-Delayed Brake Controllers

Time-delayed controllers operate based on pre-set settings that determine how much braking power is applied and how quickly it is delivered after pressing the pedal. These are generally more affordable and easier to install but may require more manual adjustment to find the right balance for different loads.

Proportional Brake Controllers

Proportional controllers provide a smoother braking experience as they automatically adjust the braking intensity based on the vehicle's deceleration rate. They offer superior performance, especially in varying terrains and conditions but come at a higher cost compared to their time-delayed counterparts.

Installation Process

Installing a trailer electric brake controller is best done by professionals who understand both the mechanical and electronic aspects involved. A professional installation ensures all components are correctly wired and calibrated for optimal performance.

During installation, technicians will typically mount the controller within easy reach of the driver’s seat so adjustments can be made while driving if necessary. They'll run wires from the controller through to your vehicle's battery and into its electrical system, connecting them with those of your trailer's brakes.
