Description
If you’re planning to tow a caravan, camper, horse float, or tradesman trailer around Victoria, there’s one piece of equipment you simply can’t afford to overlook — a portable electric brake controller.
Towing heavy loads without the right brake controller isn’t just risky — it’s illegal. In Australia, any trailer over 750kg GTM requires a compliant braking system to meet ADR (Australian Design Rule) standards and to ensure your safety on the road.
What Is a Portable Electric Brake Controller?
A portable electric brake controller is a smart device that automatically controls the braking force applied to your trailer’s wheels, based on the deceleration of your tow vehicle.
How does it work?
- When you press the brake pedal in your car or 4WD, the controller senses the deceleration using an internal inertia sensor (accelerometer).
- After that, it gives your trailer brakes a proportionate electrical signal; the more you brake, the more force is exerted on the trailer.
- This creates smooth, safe stopping and prevents the trailer from pushing or jack-knifing.
When reversing into confined spaces, proportional braking works well. Adjustable boost levels for heavier loads
LED readouts to track braking power and connection
How is it different from a hardwired controller?
Unlike a hardwired unit, a portable brake controller doesn’t require permanent wiring into your vehicle’s dashboard or fuse box. It simply plugs into the trailer wiring harness or 12V socket and can be removed or transferred to another tow vehicle in minutes.
Below is a simple diagram showing the main components:
- Controller unit with LED display
- Quick-connect harness
- Remote dial or control pad
- Plug & Tow 2-plug adapter port
- Snap-in dash mount bracket
Benefits of Using a Portable Brake Controller
Wondering why so many Australian caravan owners and tradies are switching to portable controllers?
Here are the main reasons:
No Permanent Wiring
With a portable unit, you don’t need to drill holes, run cables through the firewall, or modify your vehicle’s interior. Ideal for leased vehicles, new cars, or if you plan to upgrade your tow rig soon.
Quick Installation
Most portable controllers can be installed in less than 15 minutes. Just connect the wiring harness, mount the unit on your dash with a bracket, and you’re ready to tow.
Use Across Multiple Vehicles
If you switch between your work ute and your family SUV, you can easily move the controller. It’s the ultimate flexible solution.
Compliant and Safe
Portable controllers that meet Australian Design Rules (ADR) are fully legal for trailers over 750kg GTM.
Cost-Effective
You avoid the labour costs of hardwired installation, making portable units more budget-friendly for occasional towing setup.
Perfect for All Kinds of Trailers
From Jayco caravans to tradesman trailers, campers, and horse floats, portable brake controllers work reliably with electric braking systems on up to 3 axles.

- Instruction manual
- Optional Bluetooth module (on some models)
Having a complete kit means you don’t need to buy extra parts or run to the auto store. Everything is ready to install right out of the box.
How to Choose the Right Portable Brake Controller
Choosing the right brake controller comes down to matching your towing needs with safety, convenience, and budget. Here’s what to consider:
Trailer Weight & Size
First, check the Gross Trailer Mass (GTM) of your trailer. Light single-axle trailers can use simpler controllers, while heavy caravans and dual or triple axle trailers need units with higher amperage and adjustable boost settings. If you’re unsure, check the compliance plate or ask us for advice.
How Often You Tow
If you only tow occasionally, a mid-range model will cover you without overcomplicating things. For regular or long-distance towing, consider investing in a premium option like the REDARC Tow-Pro Liberty or Elecbrakes Wireless for smoother braking and durability.
Wireless vs Wired
Wireless controllers, such as Elecbrakes, offer fantastic flexibility—you can switch them between vehicles easily and adjust settings via an app. Wired units still plug in quickly but usually have a dash-mounted dial and can feel more traditional.
Budget & Warranty
While cheaper units might look tempting, quality matters. Look for proven brands that comply with Australian standards and include a solid warranty. Saving a little upfront can cost you dearly if the controller fails when you need it most.
Installation & Support
Always buy from a trusted supplier who can help with setup and answer questions. At TJM Bendigo, we’ll walk you through installation and show you exactly how to operate your controller so you feel confident on every trip.

FAQs about the Portable Electric Brake Controller
How do electric brakes work?
When electrical current is applied, an electromagnet is used in electronic brakes to engage the brake pads. The electrical signal that is supplied to the brake controller by pressing the accelerator button in your car powers the electric brakes on the trailer.
Do electric brakes work without a controller?
No, in order for electric brakes to work correctly, a controller is needed. The controller is in charge of delivering the electrical impulses required for the trailer’s brakes to engage. The absence of a controller renders the electric brakes inoperative, leading to potentially hazardous circumstances.
What are the two types of brake controllers?
Proportion and time-delayed brake controllers are the two primary varieties of brake controllers. Smoother and more responsive braking is achieved via proportional controllers, which apply brake force in accordance with the vehicle’s deceleration. In contrast, time-delayed controllers apply a predetermined amount of braking force regardless of the vehicle’s rate of deceleration after a predetermined amount of time.
How does a portable electric brake controller work?
While it functions similarly to a regular brake controller, a portable electric brake controller has the advantage of being easily transportable between cars. It allows the car to send signals to the electric brakes on the trailer by connecting to the electrical harness and brake pedal.
What is the function of an electric brake?
When a trailer is being towed behind a car, electric brakes help to slow it down or stop it. Electric brakes create friction on the trailer’s wheels by using electrical current to activate brake pads or shoes. This helps with deceleration and enhances overall control and safety when towing.
Do electric brakes need a battery?
Actually, for the purpose of powering the electromagnets that engage the brake assembly, electric brakes need a battery. In the event that the engine is turned off or there is an electrical breakdown between the car and the trailer, this guarantees their ability to function independently of the vehicle’s electrical system and provide dependable brakes.
