How does a breakaway system work?
Consisting of a battery mounted on the trailer and a cable connecting the trailer to the vehicle, the breakaway system is activated if the trailer breaks free, pulling the cable out of its plug with it. A switch will then trigger the battery and apply the trailer brakes to slow the trailer down.
What is surge brake?
This is accomplished via the trailer’s brakes, which can be one of two types: surge (mechanic or hydraulic), which rely on inertia to automatically slow down, or electric brakes, which require an electric connection to the tow vehicle to work. The principle behind surge (also known as override or overrun) brakes is simple.
What is proportional brake controller?

What is a trailer brake controller?
A trailer brake controller is a small electronic device that installs in your tow vehicle's cab and activates your trailer brakes via an electrical signal whenever you apply your tow vehicle brakes. This basically just means that when you hit the brakes in your car, the brake controller delivers the message to your trailer so that it can stop too.
Where should brake controllers be mounted?
This is because they are relatively boxy and bulky, and they must be mounted (often at a specified angle, in the case of proportional controllers) in your vehicle cab, right around knee height. This can be an issue if your cab is already crowded, or if you have long legs that keep bumping the brake controller.
What is a good proportional controller?
THE GOOD Proportional controllers are ideal for the majority of towing scenarios, provide the smoothest braking, and cause less wear on your braking system. You don't have to worry about your trailer braking too hard or not hard enough, which can result in a "push/pull" effect on your vehicle.
What is proportional brakes?
Proportional controllers apply the brakes in your trailer with the same force as you apply the brakes in your vehicle. That is, if you have to slam on your brakes on the highway, your trailer brakes will be applied proportionally. If you roll to a stop at a red light, your trailer will gently stop as well.
How much does a time delayed brake controller cost?
