What is Brake Controller?

Wikipedia defines this device as an OEM or aftermath mounted module or device. You will find it on the tow automobile’s driver’s side dashboard and connects a trailer’s braking system either in proportion or time delayed to the tow automobile’s brake engagement when slowing down or stopping. You don’t need a brake controller in a trailer rise braking method unless using over hydraulic or modern electrical devices. The trailer has electric friction brake actuators or electric-hydraulic trailer brake


The brake controller is the connection between the brake pedal on the automobile and the braking on the axles of a trailer. If your vehicle does not have it, you will not be able to control the weight, which may result in accidents and damage. It is designed not just for a truck or car but also for other types of vehicles in situations you can’t slow down or stop in time. An electric trailer brake control supplies electrical power from a towing car to the electric brake on a trailer. For a trailer with electrical brakes, you need a brake controller. You also need a brake controller for automatic leveling and for safety measures.


There are three types of best brake controllers available in the market. They are as follows:

  • Proportional Brake Controller

This type of brake controller makes use of a motion-sensing device to determine how fast the tow vehicle stops. It is also known as a pendulum brake controller because of the way it can sense motion. These units use the position of the pendulum in sensing the movement, and the driver needs to calibrate them before using it. As soon as the driver applies the brakes, the controller employs the same amount of power to the trailer’s brake.

  • Time-Delayed Brake Controller

This type of controller receives signal each time you engage your tow vehicle’s brakes. The signal sends power to your brakes at a pre-determined rate of intensity placed by the driver. You can adjust the rate depending on the automobile, conditions and on what the driver feels right. As the name implies, there is always a time delay between if you set on your own brakes and if the one on the trailer is activated. This type of brake controllers put more wear on the braking system, but it cost less and is easier to install as compared to proportional.

  • Hydraulic Over Electric Controller

As the name suggests it uses hydraulic pressure of the brake mechanism on a vehicle. The hydraulic power brings a current to control the electric brakes of the trailer. Some car manufacturers provide this as an OEM option, such as Ford utilizing its Ford Tow Command.

Essential Factors to Consider when Purchasing

To make it easier for you to choose the right one, keep in mind the following tips:

  • Proportional or non-proportional

The proportional brake controllers utilize various systems to sense the car’s deceleration and then use proportional power to the electric brakes. The non-proportional is time delay activated or solid state. Both provide a set amount of capacity to the trailer braking system.

  • Hydraulic-Electric Capacity

There are some brake controllers that is both hydraulic and electric. It is recommended that you choose the one that offers both kinds of capacity.

  • Voltage

This is one of the important characteristics of a brake controller that you need consider. The brake controllers are available in 12V and 24V and should match the power source of the towing vehicle. Unless indicated as 24V, most controllers use 12- volt vehicles.

  • Number of Axles

The controllers are designed to suit a specific number of axle assemblies on the trailer. It measures the total power it can provide. If the controller indicates that it can be used for 4 axles, you can also use it on any type of axle.

  • Type of Display

Generally, LED is ideal for any type of brake controllers. For a digital display, efficient power is delivered and a menu system. The latest units offer more monitoring options. Some units have LCD screens that provide specific, important warning signals to drivers and continuous diagnostics. Most of the time display is customizable, where you can set the color and language that you want.

  • Installation

The brake controllers can be installed in a cradle below the dashboard or remotely with controls sticking out of the dashboard.
