How does a brake controller determine when to apply the brakes?
A brake controller typically uses a sensor to detect when the tow vehicle is applying the brakes. This sensor can be a pressure sensor, a speed sensor, or a combination of both. When the sensor detects the tow vehicle’s brakes being applied, it sends an electrical signal to the trailer’s brakes to apply them in proportion to the tow vehicle’s braking effort.
What is the difference between a time-delayed brake controller and a proportional brake controller?
A time-delayed brake controller applies the brakes to the trailer after a delay, usually around 1-2 seconds, to prevent the trailer from swaying or jackknifing. A proportional brake controller, on the other hand, applies the brakes to the trailer in proportion to the tow vehicle’s braking effort, usually within 1-2 seconds. Proportional brake controllers are generally considered safer and more effective than time-delayed controllers.
Can I use a brake controller with my electric brakes?
Yes, most brake controllers are designed to work with electric brakes on trailers. However, it’s important to ensure that the brake controller is compatible with your trailer’s electric brakes and that the brakes are properly installed and functioning correctly.
