Redarc Electric Brake Controllers

Any responsible trailer or caravan owner knows that when you’re hauling such a huge weight, you’re hauling something else along with it – responsibility. And being a responsible trailer owner means having all the appropriate commitments and safeguards in place to ensure that your trailer is easy to control and protected in the case of unexpected complications. And, of course, this responsibility only increases with the size and weight of your load.

Within our extensive range of Redarc Electric Brake Controllers, you’ll be able to find all the protective features and nuanced control that you need to haul your trailer or caravan with total confidence.

Why Do You Need a Redarc Electric Brake Controller?

Why Do You Need a Redarc Electric Brake Controller?

When you are towing a heavy trailer or caravan behind you, it is essential to have some sort of braking system in place. Just like how your body keeps moving forward when you brake, so will a trailer or caravan – the heavier the object you’re towing, the further it’ll keep moving when you brake. That means towing a heavy load can become dangerous without brakes, especially on steep downslope inclines or in wet conditions.  

Trailers and caravans are among the largest loads you can haul. Consequently, you’re no longer simply controlling your normal vehicle when you brake, you’re also controlling the massive trailer behind it. That’s what makes a Redarc brake controller so indispensable. Allowing for finer control over two braking systems, these units make coming to a sudden halt an easier, safer, and more manageable experience.

Redarc’s extensive range of electric brake controllers also include their User-Controlled systems, Break-Safe Break-Away systems and the Tow-Pro Classic Electric Brake Controller. Not only do Redarc brake controllers suit most braking applications, they also take up very little space on the dashboard and can be easily adjusted with the turn of a switch. Redarc also produce the Tow-Pro Wiring Kits for easy installation and Switch Inserts which help to achieve an OE looking remote head on the dashboard.

The Different Types of Redarc Brake Controllers

Redarc User-Controlled Electric Brake Controller 12V

The most basic brake controller of Redarc’s expansive range, the Redarc User-Controlled Electric Brake Controller 12V makes for a perfect entry-level brake controller for your trailer’s electric brakes.


  • LED indicator glows green to let you know that the electric brakes are plugged in, or red to indicate the degree of braking set by the control knob
  • Override button so you can activate your trailer’s brakes independently of the brakes of your towing vehicle 

If your vehicle runs on 24V instead of 12V - never fear! The Redarc Electric Trailer Brake Adaptor lets you use any 12V brake controller with a 24V vehicle system, or vice versa. 

Redarc Trailer Mount Electric Brake Controller 12V

Entirely potted within silicone elastomer, the Redarc Trailer Mount Electric Brake Controller 12V is the best option when you’re looking for a trailer-mounted electric brake controller that is protected from the harsh elements you’ll often encounter during your outdoor adventures. The option of having an encapsulated brake controller is a great way to minimise the effects of both vibrations and the weather. 

Redarc Tow-Pro Electric Brake Controllers

The Redarc Tow-Pro Elite Electric Brake Controller is one of the most advanced Redarc models, offering a raft of sophisticated features not available in the more basic brake controllers. While not necessary for every trailer or caravan owner, these additional features can significantly boost your safety and confidence when you’re out on the road.


  • Offers two modes: proportional braking and user-controlled braking*
  • Compatible with all new vehicle technology
  • Compatible with both 12V and 24V systems
  • The newest generation, V3, comes with software upgrades that provide even smoother braking than the V2
  • Designed for a quick and simple installation process
  • Can fit snugly onto the thicker, curved dashboards of European cars and trucks

If you prefer to manually set the braking force on your trailer, the Redarc Tow-Pro Classic Electric Brake Controller is the perfect option for you. The Redarc Tow-Pro Classic offers user-controlled braking to give you absolute control of the trailer or caravan at all times.


  • User-controlled braking with an adjustable control knob - no matter how fast or slow you brake, the trailer will brake exactly as set so you’ll always know what to expect!
  • Electric/hydraulic operation
  • Compact size with LED status indicator
  • Made for 12V systems but can be adapted to 24V systems with the Redarc Electric Trailer Brake Adaptor

*Proportional brake controllers sense the deceleration of the vehicle and apply a suitable amount of force to achieve gentle and smooth braking – perfect for highway driving, fragile loads and for drivers who prefer to “set and forget”. User-controlled brake controllers are designed for off-road driving where the same amount of braking force is applied every time and is especially suitable to sandy or rocky paths.

Redarc Break Away Controller 12V DC

The Redarc Break Away Controller 12V DC is designed to take over the brakes and lights of your trailer in cases where it becomes separated from your vehicle. This provides a measure of protection in case of runway trailers, both preventing them from rolling away and notifying drivers behind you that the trailer is coming to a stop.

The benefits of such a controller are varied and fairly obvious, protecting both your trailer and other vehicles on the road. Not only is this a matter of personal responsibility, but legal requirements in most states and territories make a break away controller like the Redark Break Away Controller 12V DC a must-have.

Installing Your Brake Controller

Setting up your Redarc Brake Controller is an easy, user-friendly experience. However, there are still a few pitfalls to bear in mind to prevent avoidable problems from cropping up. Redarc’s brake controllers are built with versatility at the forefront of the design process, meaning they can be mounted in any orientation that suits your individual vehicle setup.

However, one thing to bear in mind is that the mounting you use to attach your controller needs to be secure. This is of particular importance for models like the Redarc Tow-Pro Elite Brake Controller, which uses advanced sensors to gauge the inertia of your trailer. Loose and unsecure mounting can lead to false readings that may trigger the automatic brake and light function unnecessarily.

This can obviously be both a performance and safety issue, so ensuring your mounting and screws are all tight and secure must be top of your list of priorities.
