Electric Brake Controllers

What Is an Electric Brake Controller?

An electric brake controller regulates the brakes on a trailer in relation to the tow vehicle. When you press the brakes in your tow vehicle, the controller automatically sends an electrical signal to the trailer’s brakes. This synchronisation is important for maintaining safety, helping to prevent the trailer from pushing the tow vehicle during stops or turns.

 

Types of Electric Brake Controllers

Understanding the different types of electric brake controllers can help you make a more informed decision:

1.   Proportional / Inertia-based Brake Controllers

These monitor the inertia of the tow vehicle and adjust the braking force proportional to the vehicle’s speed and braking intensity, resulting in a smooth braking experience.

2.   Time-Delayed Controllers

These units apply a fixed amount of braking force after a pre-set delay when the tow vehicle begins to slow down. They’re generally more affordable but may not provide the same level of responsiveness as proportional controllers.

3.  User-controlled / Manual Override Controllers

These allow drivers to adjust the braking power when needed, providing greater control in varying road conditions or when additional braking power is needed.

4.  Break-safe / Break-away Systems

These specialised brake controllers activate the trailer brakes in case it becomes disconnected from the tow vehicle, enhancing safety during emergencies.

 

Key Features to Compare

When selecting an electric brake controller, compare these features:

Braking Modes and Responsiveness

Different controllers offer different modes that can affect how rapidly and effectively they react to your braking. Select the one that matches your driving style and towing conditions.

Voltage Compatibility

Choose a brake controller that is compatible with your vehicle's electrical system, normally either 12V or 24V.

Maximum Trailer Weight / Gross Trailer Mass (GTM) Limits

Check the brake controller's capacity to handle the weight of your trailer. Exceeding these limits may compromise safety.

Installation Requirements

Check for wiring complexity, switch inserts, and any additional wiring kits you may need for setup.

Ease of Use

Features like a dashboard control, override mechanisms, and other user-friendly settings will improve your experience.

Safety Features

Features such as sway control and warning lights will alert you to potential safety hazards, helping to prevent incidents.

 

How to Choose the Right Electric Brake Controller

Consider these aspects when choosing your brake controller:

Towing Weight & Trailer Type

Select the brake controller appropriate for the weight and dimensions of your trailer.

Vehicle Capability & Electrical System

Match your vehicle’s towing capacity and electrical system with a compatible brake controller.

Terrain and Frequency of Towing

If you're towing in hilly terrain or towing often, choose a more advanced, responsive brake controller.

Budget vs Premium Features Trade-offs

Evaluate your budget against the features you need. While premium models might offer more functions, a mid-range option could suffice for light towing.

 

Installation & Maintenance Tips

Proper installation and maintenance extend the lifespan and performance of your electric brakes for your caravan. Follow these tips for safer, more efficient towing:

1.          Use quality wiring and connectors and avoid exposed wiring.

2.          Mount the controller in a secure, accessible location.

3.          Periodically check wiring, connections and settings.

 Regularly maintain and inspect trailer brakes to ensure they match your brake controller’s performance.
