How to Install Trailer Brake Controller, Step by Step !

How to Install Trailer Brake Controller – When hauling a big load, an adjustable brake controller may be necessary if your trailer has electric brakes. Examine the various brake controller kinds and discover how to install one.

What Is a Brake Controller?

In order to brake, a trailer brake controller modifies driving inputs. It comes on when you apply pressure to the towing vehicle’s brake pedal. Commercial vehicles are required by federal law to have a brake controller when towing a trailer that weighs more than 3,000 pounds.

The voltage output of a brake controller is usually adjustable. This function determines the braking force and gain amount based on the weight and type of the trailer as well as the weather. For instance, modest braking force is necessary while stopping an empty trailer to prevent tire damage and brake lockup. However, in order to shorten stopping distances, fully loaded trailers require more effort when using the brakes.

Usually, there’s an additional manual method for applying the brakes. This substitute feature aids in maintaining control or lessening trailer sway when driving on slick terrain.

Various Brake Controller Types

Brake controllers are available in many designs. Time-delayed and proportional brake controllers are the two most widely used types.

Time-Delayed Brake Controller

The user-specified capacity of the time-delayed brake controller is dependent on the weight of the load and trailer. The controller’s manual “sync” option modifies the timing and power of the brakes. The driver applies the amount of braking when you press the brake pedal. Should you adjust it too low, the trailer slows down because your tow car brakes more than is necessary. An excessively high setting causes the trailer to brake harder than is necessary.

Even while this method offers a cheap, safe way to tow, it’s not the best option for regular towing. Rather, it works best for drivers who don’t tow very often.

Proportional Brake Controller

The trailer brakes engage simultaneously with the towing vehicle’s brakes, according to the proportional brake controller. The brakes on the car and trailer last longer with this setup. It is more responsive and speedier as well, but it is not free.

How to Install a Trailer Brake Controller

  • Unplug the negative battery terminal. This precaution helps shield the car’s electronics from harm and avoid injuries to individuals.
  • Locate where you want to place your brake controller. A lot of people place it slightly below or on the side of the steering wheel. It remains out of the way even though it is still visible in this spot. Mounting it above your dashboard is another option.
  • Drill the holes required to locate the brake controller using the mounting bracket as a template. Drill carefully, and if you find a vulnerable place, change the position. To examine what’s behind the panel, we advise removing it first.
  • After aligning the brake controller bracket with the holes, use the provided fasteners to tighten it. Avoid overtightening the screws to avoid stripping the holes.
  • Tighten the brake controller onto the mounting plate.
  • Plug the controller into your car using the harness that is relevant to your car. The brake controller receives one end, while the factory harness beneath the dashboard receives the other.
