But at what weight do you need electric brakes? In this article, we’ll delve into the world of electric braking systems, exploring the key factors that determine when they’re required, how they work, and the benefits they provide.

Introduction to Electric Brakes

Electric brakes are a type of braking system used in trailers and other towed vehicles. They work by using an electric current to activate the brakes, which are typically drum brakes or disc brakes. The system consists of a brake controller, which is installed in the tow vehicle, and electric brake assemblies, which are installed on the trailer. When the driver presses the brake pedal in the tow vehicle, the brake controller sends an electric signal to the trailer’s brake assemblies, causing them to engage and slow the trailer down.

How Electric Brakes Work

The process of engaging electric brakes involves several key components. The brake controller is the brain of the operation, sensing the deceleration of the tow vehicle and sending a proportional electric signal to the trailer’s brake assemblies. The brake assemblies, in turn, use this signal to apply the brakes, with the amount of braking force determined by the strength of the electric current. This proportionality is crucial, as it allows the trailer to slow down at the same rate as the tow vehicle, reducing the risk of jackknifing or trailer swing.
