When it comes to towing a trailer or a caravan, safety is of utmost importance. One of the most critical components of the towing system is the brake controller. A brake controller is a device that helps to control the braking system of the trailer, ensuring that it stops smoothly and evenly when the tow vehicle brakes. Among the various types of brake controllers available, a proportional brake controller is a popular choice among tow vehicle owners. In this blog post, we will delve into the world of proportional brake controllers, exploring what they are, how they work, and their benefits.
What is a Proportional Brake Controller?
A proportional brake controller is an electronic device that controls the braking system of a trailer or caravan. It is designed to work in conjunction with the tow vehicle’s braking system, ensuring that the trailer brakes are applied in proportion to the tow vehicle’s braking force. This means that the trailer brakes will be applied more or less depending on the intensity of the tow vehicle’s braking.
The proportional brake controller uses a sensor to detect the tow vehicle’s braking force and applies the trailer brakes accordingly. This results in a smoother and more controlled braking experience, reducing the risk of trailer sway and improving overall safety.
Proportional brake controllers are available in various types, including wired and wireless models. Wired models require a connection to the tow vehicle’s electrical system, while wireless models use a wireless connection to communicate with the tow vehicle.
How Does a Proportional Brake Controller Work?
A proportional brake controller works by using a sensor to detect the tow vehicle’s braking force. This sensor is usually a pedal position sensor or a wheel speed sensor, which sends a signal to the brake controller. The brake controller then uses this signal to apply the trailer brakes in proportion to the tow vehicle’s braking force.
The brake controller uses a complex algorithm to determine the correct amount of braking force to apply to the trailer. This algorithm takes into account various factors, including the weight of the trailer, the speed of the tow vehicle, and the braking force applied by the tow vehicle.

The brake controller then sends an electrical signal to the trailer’s brake actuator, which applies the brakes to the trailer. The trailer brakes are applied in proportion to the tow vehicle’s braking force, ensuring a smooth and controlled braking experience.
Benefits of a Proportional Brake Controller
A proportional brake controller offers several benefits to tow vehicle owners, including:
- Improved safety: Proportional brake controllers help to reduce the risk of trailer sway and improve overall safety.
- Smaller trailer sway: By applying the trailer brakes in proportion to the tow vehicle’s braking force, proportional brake controllers help to reduce trailer sway.
- Improved braking performance: Proportional brake controllers ensure that the trailer brakes are applied smoothly and evenly, resulting in improved braking performance.
- Reduced wear and tear: Proportional brake controllers help to reduce wear and tear on the trailer brakes, extending their lifespan.
- Increased towing capacity: Proportional brake controllers enable tow vehicle owners to tow heavier trailers with confidence.
Types of Proportional Brake Controllers
There are several types of proportional brake controllers available, including:
- Wired proportional brake controllers: These controllers require a connection to the tow vehicle’s electrical system.
- Wireless proportional brake controllers: These controllers use a wireless connection to communicate with the tow vehicle.
- Electronic proportional brake controllers: These controllers use electronic signals to control the trailer brakes.
- Pneumatic proportional brake controllers: These controllers use compressed air to control the trailer brakes.
Installation and Maintenance of Proportional Brake Controllers
Proportional brake controllers require proper installation and maintenance to ensure optimal performance. Here are some tips to keep in mind:
- Read the manufacturer’s instructions carefully before installation.
- Ensure that the brake controller is properly connected to the tow vehicle’s electrical system.
- Test the brake controller regularly to ensure it is functioning properly.
- Check the brake controller’s wiring and connections regularly for damage or wear.
- Replace the brake controller’s fuses regularly to ensure optimal performance.
