Choosing The Right Electric Brake Controller

Types Of Brake Controllers: Time-Delayed And Proportional

When it comes to electric brake controllers, there are two main types to choose from: time-delayed and proportional. Understanding the differences between these two types will help you determine which one is right for your needs. Here are the main points to consider for each type:

Time-delayed brake controllers:

  • Act based on a pre-set time delay (usually from 1 to 10 seconds) after you apply the brakes.
  • More affordable option compared to proportional brake controllers.
  • Best suited for tow vehicles with similar loads and terrains who use their trailers infrequently.

Proportional brake controllers:

  • Continuously adjust the brake output depending on changes in the tow vehicle’s braking system when applied.
  • Greatly enhance the trailer’s stability and braking performance, owing to their superior precision and accuracy.
  • Ideal for towing vehicles with varying loads, terrains, and weather conditions, especially those who spend significant amounts of time towing heavy trailers.

Factors To Consider When Choosing An Electric Brake Controller

Before selecting an electric brake controller, you should first consider a few key factors to ensure you choose the right one for your specific needs. Here are the most critical points to consider:

Trailer weight and size:

  • The electric brake controller you choose must be capable of handling the weight of your trailer. Always check if the brake controller is rated for the maximum weight of your trailer.
  • Large trailers will require proportional brake controllers due to the increased stopping power required.

Type of tow vehicle:

  • Some electronic brake controllers are more compatible with specific tow vehicles than others. Before purchasing, make sure the controller you choose is compatible with your specific tow vehicle model.

User experience and preferences:

  • Choose a brake controller that you will find easy to use and navigate. Look for models with clear manuals, simple displays, and easy-to-read settings. Some models even come with smartphone apps, which makes setup and configuration much more comfortable.

By taking these factors into careful consideration, you will undoubtedly choose the electric brake controller that best suits your needs and budget.

Wiring Your Electric Brake Controller

Basic Knowledge Of Electrical Wiring Required

Before wiring an electric brake controller, it’s essential to have basic knowledge of electrical wiring. Having knowledge of electrical systems can make the installation process easier and faster. If you’re not confident in your electrical knowledge, consider seeking help from a professional installer.

Tools Required For Smooth Installation

To wire an electric brake controller, you will need several tools such as a screwdriver, pliers, wire stripper, and crimping tools. It’s important to have these tools on hand to ensure a smooth installation process. Other tools you may need include electrical tape, zip ties, and a voltmeter.

Step-By-Step Guide For Wiring A Brake Controller

  • Connect the brake controller to the tow vehicle’s power source by using a heavy-gauge wire. Typically, this wire is located under the dash on the driver’s side of the vehicle.
  • Connect the controller to the brake switch using a brake switch circuit wire. The brake switch is typically located near the brake pedal.
  • Connect the controller to the trailer brake magnets using the brake output wire. This wire goes to the brakes on the trailer and activates them when the tow vehicle brakes are applied. Be sure to connect the brake output wire to the correct brake on the trailer and use a circuit tester to ensure the connections are secure.
  • Test the brake controller before hitting the road. Ensure that the brake controller is properly synced with the trailer’s brakes and that the brakes are working correctly.

By following these simple steps, you can wire an electric brake controller and ensure that your trailer’s brakes are working correctly while towing. Remember to always follow the manufacturer’s instructions and consult a professional installer if you’re not confident in your electrical wiring skills.
