Brake Controllers

Why is a brake controller needed?

Having a brake controller while towing an RV is essential for safety and control. It synchronizes the RV's electric brakes with your vehicle's braking system, allowing for smoother, more stable stops. This not only helps prevent dangerous situations like jackknifing or trailer sway, especially during sudden stops or downhill driving, but it also reduces wear on your tow vehicle's brakes. In many regions, brake controllers are also a legal requirement for towing trailers over a certain weight, making them a crucial component for both compliance and peace of mind on the road.

How to configure your brake controller.

• Install the Brake Controller

  • Mount the unit in a location that’s easily accessible but out of the way (usually under the dash near the steering column).

  • Connect the brake controller wiring to your vehicle, either via a factory brake controller harness or manual hardwiring.

• Connect to Trailer

  • Plug the trailer’s wiring harness into your vehicle’s tow connector.

  • Ensure all lights and the electric brakes are working properly.

• Power On and Initialization

  • Start your vehicle to power the brake controller.

  • Most controllers will self-check and display a code or “.c.” (connected) when the trailer is detected.

• Set the Brake Type (if applicable)

  • Some controllers let you choose between electric or electric-over-hydraulic brakes — select the correct type for your trailer.

• Adjust Trailer Gain (Output Strength)

  • Start with the gain at a mid-range setting (around 5.0 on a scale of 0–10).

  • Drive slowly (10–15 mph) on a flat surface and manually apply the trailer brakes using the controller’s manual lever.

  • Adjust the gain up or down so the trailer brakes apply firmly without locking up or pulling.

• Adjust Brake Sensitivity/Boost (if available)

  • Increase boost if you’re towing a heavier trailer or if the brakes feel delayed.

  • Decrease it if braking feels too aggressive or jerky.

• Test Under Normal Driving Conditions

  • Make several test stops from various speeds, adjusting gain and boost for smooth, synchronized braking.

  • Ensure the trailer does not push or jerk the tow vehicle during braking.

• Re-check and Fine-tune Regularly

  • Especially if load conditions change (e.g., added cargo or passengers), re-adjust gain settings as needed.

• For more specific instructions refer to your brake controller's user manual or ask your local dealerships service or parts department.
