Your Guide to Electric Trailer Brake Parts

electric trailer brake parts
TABLE OF CONTENTS

Whether you’re towing a trailer for work or pleasure, you’re asking a lot of your vehicle. Stopping with increased weight and force behind your vehicle is more challenging, so you want the best brake system on board. Fitting your electric trailer brake system with the best parts can give you real peace of mind.

Choosing Electric Trailer Brake Parts: What You Need to Know

Electric trailer brake parts are electric brake system components used for commercial, utility, and cargo trailers, RVs, and many other trailers. These parts may sit on your towing vehicle or trailer. An electric trailer brake system consists of the following parts:

  • A trailer wiring end plug
  • A mating plug on the tow vehicle
  • An electronic brake controller
  • Left and right electric brake assemblies
  • Drum and hub assemblies
  • An emergency breakaway kit featuring a battery with box, trickle charger, and breakaway switch — this will automatically activate the trailer brakes if the trailer detaches from your vehicle
  • An end plug connector

Make sure you’re buying parts compatible with your existing components. For example, if your trailer wiring end plug has a six-pin round pin connection, your towing vehicle needs a mating plug with the same connection. Consider your own abilities when choosing your components. Some modern electronic brake controllers have pre-wired plugs which are easier to install. Alternatively, an auto electrician can do the work for you.

How Do Electric Trailer Brakes Work?

Electric trailer brakes receive a signal from the brake controller mounted in the tow vehicle. When they receive the signal, electromagnets trigger the braking mechanism via the drums. The brake controller and brake light circuit control electricity to the brakes for a smooth braking experience.

Do You Need an Electric Trailer Brake System?

It depends where you live and what you’re towing. Small utility trailers often do not have their own brakes because they’re not designed to carry heavy loads. The tow vehicle’s brakes will be sufficient. Larger, heavier trailers intended for heavier loads will usually have their own brakes, particularly if they have more than one axle.

Some states have laws requiring motorists to have independent brake systems, such as electric brake systems, when towing trailers with heavy loads. In these states, you must have an electric trailer brake system or similar to avoid fines.

Electric Trailer Brake Systems vs. Mechanical Trailer Brake Systems

Electric trailer brake systems offer a much smoother braking experience than traditional mechanical trailer brake systems. While mechanical trailer brake systems have become smoother in recent years, electric trailer brake systems are still prized for their smoothness. These systems limit pressure on the brakes of your towing vehicle, helping them last longer. Through the brake controller, motorists can reduce swaying. This is a real benefit on hills and areas with high winds, especially for people new to towing.

What To Look For In Electric Trailer Brake System Parts

Electric trailer brake system parts have an important role in keeping you, your loads, and other road users safe, so it’s important they’re up to the task. You can feel confident purchasing from established brands such as Tekonsha, Dexter, and REDARC who have made electric trailer brake parts for years. However, there are some new brands entering the space creating electric brake controllers with Bluetooth and wireless technology. If you want a cutting-edge controller, it may be worth trying an innovative new brand.

Reviews can help you feel more comfortable in your choice. Read the feedback that other customers post to determine the quality of the parts you’re considering purchasing. If parts typically receive positive feedback, you can feel confident they’ll work well for you. Here are some of the electric trailer brake parts we love.
