The trailer brake controllers vary in the number of brakes they can control. Choosing the best trailer brake controller may not as simple as it may be. This buying guide will help you find the right brake controller for your towing needs. 


How Does A Brake Controller Work?

Brake controllers work on a definite way. The magnet is activated when power comes from your own brake controller. It really is attracted to the inside smooth face of the revolving brake hub. The rotating centre causes the magnet to revolve as shown (Magnet is mounted on a good lever that rotates). When it turns it causes the both brake shoes to pass on and then apply your brakes.

The brake controller gets installed into the car (on or close to your dashboard). It also controls the power that gets delivered to the magnet at the wheel.

The controller includes a direct connection to the battery for the actual source of power. It has a link with the stop light also, typically from the switch at the brake pedal. This explains to the machine to supply capacity to the magnet, with a direct cable from the controller. An earth is required also.

Time delayed brake controller


This type applies a preset breaking power and It has a delay function once the brake pedal engages. The time-delayed brake controllers can be installed in any part since they do not have sensors that determine whether a vehicle will go downhill or uphill. Aside from that this type of brake controller is much easier to install as compared to proportional models.

Hydraulic over electrical controller


This type of brake controller makes use of the hydraulic pressure mechanism on a car. The hydraulic power provides a current to control the electric brakes of the trailer. Some vehicle manufacturers give this as an OEM option, like Ford using its Ford Tow Command.
