What is a brake controller?
A restriction controller is an electronic device that regulates the electric trailer brakes. It allows the driver to activate and monitor trailer brake activity from the cab of the vehicle.
A brake controller mounts in the cab of the vehicle and generally has a few different controls, such as an interface to view braking information and buttons to command the output and manual activation. Trailer brake controllers come in many different styles and capacities.

Time Delay vs Proportional
At that place are 2 bones types of brake controllers: time-delay and proportional or inertia-based. Each type is classified by the method of activation the restriction controller uses.
Time-Delay Operation
A time-delay brake controller operates on very elementary electrical principles. As soon as the driver presses the brake pedal, the time-based brake controller activates the trailer brakes, applying an increasing amount of ability, fixed over time. This is chosen proceeds.
The gain setting of a fourth dimension-delay restriction controller tin can be adjusted by the driver to accommodate each specific trailer. Notwithstanding, the fourth dimension-delay approach is not every bit precise equally the proportional method.
Proportional Operation
A proportional or inertia-based brake controller uses an electric circuit called an accelerometer to sense changes in momentum. When the driver presses the brake pedal, the brake controller applies power to the trailer brakes in proportion to the vehicle'south momentum.
Proportional brake controllers provide polish stops and efficient braking. This is especially credible when braking on a colina. If traveling upward a hill, the controller applies less power, and if traveling downwards, information technology applies more than ability.

How to Arrange Trailer Brake Controller: 6 Steps
Footstep i: Plug in the trailer wiring harness
With your trailer coupled to your vehicle, the first stride when towing with a brake controller is to make sure the trailer wiring harness is plugged into your vehicle. A brake controller requires power from the vehicle and a connection to the trailer brakes for proper towing.
During setup, brand sure your vehicle and trailer are parked on a level surface. Also, make certain you lot are in a safe, open expanse with plenty of stopping distance and no other traffic around.
Step ii: Permit the brake controller to calibrate
With the trailer plugged in, the restriction controller may need to exist calibrated. Most brake controllers are self-calibrating. Others do not crave calibration at all.
Typically, self-calibrating restriction controllers will flash a light or signal to betoken when the unit is calibrating and when scale is complete.
Step 3: Select personal settings
Some restriction controllers come with personal settings that tin can be adapted to your preference, such as the angle of the interface, the effulgence of the screen and fifty-fifty the location of the brake controller itself.
Be sure to conform all of these settings before driving.
Step iv: Ready the maximum output
Maximum output is the maximum amount of power the brake controller will apply to the trailer brakes. Y'all will need to fix this level and suit it depending on the load size.
To adapt your brake controller output, printing and hold the vehicle brake pedal. Set the output to the starting value specified in the instructions.
Then, in an open area, test the trailer brakes by driving frontward at almost 25 mph and applying the brakes. If the vehicle stops too slowly, increase the maximum output. If it stops too abruptly or locks up, reduce the output.
Stride 5: Adjust the sensitivity level
Sensitivity is how aggressively your brake controller will apply the brakes. You can gear up sensitivity by testing the trailer brakes again.
Bulldoze forrad at about 25 mph and press the brake pedal. If the vehicle stops too slowly, increase the sensitivity setting. If it stops besides abruptly, lower the sensitivity.
Equally functioning becomes more comfy, you tin test braking at diverse speeds to ensure smoothen stops in any weather condition.
Step half dozen: Manually activate brakes as needed
Well-nigh trailer brake controllers come with a manual activation push. This allows yous to activate the trailer brakes whenever desired, without applying the vehicle brakes.
Transmission trailer brake activation can be useful for correcting small-scale trailer sway and gradually slowing down on a steep loma or before stops.

Practice I need a trailer restriction controller?
If you're asking yourself: Practise electric trailer brakes piece of work without a controller? The answer is, no. Electric trailer brakes do not work without a brake controller. If your trailer is equipped with electric brakes, y'all will need a brake controller to tow.
However, some trailers are equipped with surge brakes. These are a hydraulic braking system that uses the trailer's ain weight and momentum to activate the brakes. Unlike electric trailer brakes, they do non crave a brake controller or fifty-fifty an electric connection to the vehicle.

Towing Tip!
If yous have a trailer shop adjust your brakes, have them lubricate your wheel bearings, cheque your wheel basics and audit your tires and valve stems at the same time.
FAQs
How does a trailer brake controller piece of work?
A trailer restriction controller uses electricity from the tow vehicle to use a specific corporeality of power to the trailer brakes. It uses electrical circuits and trailer gain settings to regulate the amount of braking power. Some brake controllers have circuits that respond to the vehicle'southward momentum while towing. Others employ ability on a fixed increasing calibration and level off at a maximum output, based on parameters gear up by the driver.
How to Adjust Trailer Brake Controller
With your trailer coupled to your vehicle, the start step when towing with a restriction controller is to make sure the trailer wiring harness is plugged into your vehicle.
Annotation: During setup, make sure your vehicle and trailer are parked on a level surface. Likewise, make sure you are in a safety, open area with enough of stopping distance and no other traffic effectually.
The next pace is allowing the brake controller to calibrate. With the trailer plugged in, the brake controller may demand to be calibrated. Most restriction controllers are cocky-calibrating. Others do not require calibration at all. Next, you should select and adjust personal settings, such every bit bending of the interface, brightness of the screen, etc. before driving. The side by side matter you should do is set the maximum output. To do then, press and hold the vehicle brake pedal. Set the output to the starting value specified in the instructions. Then, in an open area, test the trailer brakes past driving frontward at about 25 mph and applying the brakes. If the vehicle stops too slowly, increment the maximum output. If it stops also abruptly or locks up, reduce the output.
The following step is to accommodate the sensitivity level. You can practise so by driving forward at about 25 mph and pressing the brake pedal. If the vehicle stops also slowly, increment the sensitivity setting. If information technology stops too abruptly, lower the sensitivity. The final step for adjusting the restriction controller is to manually activate the brakes as needed. Most trailer brake controllers come with a manual activation button. This allows you lot to activate the trailer brakes whenever desired, without applying the vehicle brakes.
How practise you lot calibrate a trailer brake controller?
To calibrate a brake controller, make certain the vehicle is parked on a level surface. And then, plug your trailer into your tow vehicle. The brake controller will then calibrate. Near brake controllers are self-calibrating. After calibration, some adjustment may be required to best fit the vehicle, trailer and load size.
What is the all-time setting for trailer brake controller?
The best setting for a brake controller is 1 that will match the trailer and load size. Begin by selecting the proceeds level and sensitivity recommended by the manufacturer. Then, test the brake controller and brakes. If more gain or sensitivity is needed, adjust accordingly.
What is trailer gain?
Trailer gain is the amount of power a brake controller applies to the trailer brakes. It is equal to the maximum amount of stopping force for the trailer. As the vehicle brake pedal is practical, the gain tells the restriction controller how much electrical ability to apply to the trailer brake electromagnets.
What should my trailer proceeds be set at?
Trailer gain should be set up based on the trailer and load size. For larger trailers, use a college gain setting. For smaller trailers, a lower proceeds setting should be used to avoid restriction lockup.
How to set trailer brake gain
To set trailer brake gain, showtime with the values specified by the manufacturer. Exam your trailer brakes at 25mph. If the vehicle stops slowly, increase the trailer brake proceeds. If the brakes lock up, decrease the gain.
