The importance of high-quality traction and electric braking

You may have realized that more than just the tractor's brakes are required to stop the vehicle and its trailer within the appropriate time frame. Considering the weight and speed of the trailer, it is evident that the trailer also needs to tilt using its braking force.
This is achieved through the trailer brakes, which can be one of two types: surge (mechanical or hydraulic), which relies on inertia for automatic deceleration, or electric brakes requiring an electrical connection to the tractor. The principle behind the surge (also known as override or overspeed) brake is simple.
The coupling includes a sliding shaft connected to the traction ball. Due to vehicle deceleration, the axle slides when pushed and applies pressure directly to the mechanical linkage (mechanical brake) or the linkage connected to the hydraulic cylinder, thereby generating hydraulic pressure on the braking system (hydraulic brake). These often appear on camping trailers or boat trailers.
Electric trailer brakes may cause wear and slow the trailer by activating the electromagnetic brake drum. When the surge brake operates independently, the electric trailer brake must be connected to the power supply of the towing vehicle and adjusted by the brake control unit or electric brake controller.

Here are the steps on how to use an electric trailer brake:

1. Install the brake controller. This is usually done by a professional, but you can also do it yourself if you follow the instructions that come with the controller.
2. Connect the brake controller to the trailer. The controller will have a plug you need to connect to the trailer's brake wiring harness.
3. Set the brake controller's gain. The gain setting determines how much braking force is applied to the trailer when you apply the brakes in your tow vehicle. You must experiment with different settings to find the one that works best for your trailer and towing conditions.
4. Use the brake controller. When you apply the brakes in your tow vehicle, the brake controller will apply the brakes on the trailer in proportion to the amount of braking force you use.

Here are some additional tips for using an electric trailer brake:

• Start with a low gain setting. This will help you avoid applying too much braking force to the trailer, which could cause it to fishtail or jackknife.
• Increase the gain setting as needed. If you find that the trailer is not breaking as much as you would like, you can increase the gain setting.
• Be careful when using the manual override. The manual override allows you to apply the trailer brakes without applying the brakes in your tow vehicle. This can be useful in an emergency, but it is essential to use it carefully to not overload the trailer brakes.

Here are some answers to frequently asked questions about electric trailer brakes:

• What is the difference between electric trailer brakes and hydraulic trailer brakes? Electric trailer brakes use electricity to apply the brakes, while hydraulic trailer brakes use hydraulic fluid. Electric trailer brakes are generally easier to install and maintain than hydraulic ones.
• How often should I adjust my trailer brake controller? You should adapt your trailer brake controller whenever you change the weight of your trailer. You may also need to adjust the gain setting if you tow in different conditions, such as on hills or wet weather.
• What should I do if my trailer brakes are not working correctly? If your trailer brakes are not working properly, you should have them checked by a qualified technician. Do not tow your trailer with malfunctioning brakes.
