Frequently Asked Questions
What is the difference between proportional and time-delayed brake controllers?
Proportional brake controllers sense the deceleration of your tow vehicle and apply the trailer brakes with a corresponding force, resulting in smooth, synchronized stops. Time-delayed controllers, conversely, apply the trailer brakes after a preset delay and at a predetermined force, regardless of how hard or fast your tow vehicle is braking. Proportional controllers generally offer superior safety and a more comfortable towing experience.
Do I need a brake controller for my trailer?
Most states and provinces require a brake controller for trailers exceeding a certain weight, typically 1,500 to 3,000 pounds, depending on local regulations. Even if not legally required, it’s highly recommended for any trailer with electric brakes to ensure safe and controlled stopping, reduce wear on your tow vehicle’s brakes, and enhance overall stability.
How do I install an electronic brake control module?
Installation typically involves mounting the module in an accessible location in your vehicle’s cabin, usually under the dash, and connecting it to your vehicle’s wiring harness. Many modern vehicles come with a factory-installed brake control harness connector, which simplifies installation using a vehicle-specific plug-and-play adapter. If your vehicle lacks this, hardwiring into the brake light switch, battery, and trailer connector wiring may be necessary. Always consult your vehicle and brake controller manuals.
What is the 'boost' feature on some brake controllers?
The ‘boost’ feature, found on some proportional brake controllers, allows you to increase the initial braking power applied to the trailer brakes. This can be particularly useful when towing heavy loads, going downhill, or when you desire a more aggressive initial braking response. It provides an extra surge of power to help overcome the inertia of a heavy trailer, ensuring more confident stops.
Can I use an electronic brake controller with hydraulic trailer brakes?
Standard electronic brake controllers are designed for trailers equipped with electric brakes. Trailers with hydraulic surge brakes operate independently of the tow vehicle’s electrical system, using the momentum of the trailer to activate its brakes. For trailers with electrically-actuated hydraulic brakes, a specific type of electronic brake controller designed for electric-over-hydraulic systems is required.
