Trailer brake controller

Okay kiddo! Today we're going to talk about something called a trailer brake controller. Remember how Mom or Dad's car has brakes to help it stop when they step on the pedal with their foot? Well, when they're towing a trailer behind the car, the weight of the trailer can make it harder to stop quickly.

That's where the trailer brake controller comes in! It's a special device that helps the driver to control the electric brakes on the trailer. The controller is usually mounted on the dashboard of the car or truck and has a lever or button that the driver can use to apply the brakes on the trailer.

When the driver pushes the brake pedal on the car, the trailer brake controller sends a signal to the electric brakes on the trailer and applies them at the same time. This can help the driver to stop the whole rig faster and safer, especially when they're driving on steep hills or in bad weather conditions.

So, in short, the trailer brake controller is a helpful tool that lets drivers apply the brakes on the trailer when they need to stop their car and trailer together, making it easier to stay safe while towing heavy loads.
