10 Best Brake Controllers 2026 in the United States

The Tekonsha 90160 Primus IQ Electronic Brake Control is a solid choice for those in need of a reliable brake controller, especially for trailers. One of its standout strengths is the Plug-N-Play feature, which simplifies installation, although it does require a T-connector, sold separately, to connect to your vehicle. Its digital LED readout displays diagnostics, making it user-friendly by alerting you to any issues. The controller also works proportionally, even in reverse, adding convenience and safety when backing up. Plus, it includes a Boost feature that enhances braking control, which can be particularly beneficial when towing heavier loads.

There are a few drawbacks to consider. While the self-diagnostics and LED readout are helpful, new users may need some time to familiarize themselves with these features. The need for a separate T-connector could be an inconvenience for buyers who expect an all-in-one solution. Additionally, while the Primus IQ has a universal fit, it’s always good to ensure compatibility with your specific vehicle and trailer setup.

This brake controller balances ease of use with solid performance, making it particularly suitable for everyday users and those who may be less experienced with trailer towing.

The Tekonsha 90195 Prodigy P3 is a proportional electric brake controller designed for trailers with 1 to 4 axles, capable of handling 2 to 8 brakes. It is compatible with many popular truck and SUV brands like Ford, GM, Chevy, Dodge, RAM, Toyota, and Jeep, making it a versatile choice for most towing setups. Its proportional braking technology automatically matches the trailer's braking force to how hard you press your vehicle’s brakes, providing smoother and safer stops.

The front-facing color LCD display is easy to read and shows real-time information and alerts, which helps in monitoring brake performance and quickly adjusting settings as needed. Additionally, the device can save up to five different brake settings, which is useful when towing multiple trailers with the same vehicle. The manual lever allows independent application of trailer brakes, offering extra control in challenging situations. The boost function delivers additional braking power, beneficial when hauling heavier loads.

One consideration is that the wiring harness required for installation is sold separately, which may increase the setup cost and complexity for users unfamiliar with vehicle wiring. Although installation is generally straightforward with the correct harness, those new to such tasks might prefer professional assistance. The compact size and clear controls contribute to its user-friendliness, but it is important to note that it is designed only for trailers up to 4 axles, so it may not be suitable for very large trailers. With strong braking performance and a reputation for reliability, the Prodigy P3 is a feature-rich option that balances ease of use with functionality.

The CURT 51181 Echo Kit is a portable and user-friendly trailer brake controller designed for trailers with 1 to 2 axles (up to 4 brakes). Its standout feature is the Bluetooth connection to your smartphone, which turns your phone into the control interface through an app. This means the controller doesn’t have a traditional screen but relies on your phone for display and adjustments. This can be convenient but requires you to manage settings safely, especially avoiding changes while driving.

Installation is impressively simple — it just plugs into the trailer’s 7-way connector with no tools or extra wiring needed, making it easy to move between vehicles. The controller uses a built-in accelerometer to provide smooth, responsive braking and works well even if your phone screen locks or calls come in. It also includes a manual override button for immediate brake activation. Compatibility is broad, working well with cruise control, anti-lock brakes, and low-voltage systems.

Because it depends on your phone for control, it may not suit users who prefer a standalone device with a dedicated display. This makes it a great choice for those seeking a flexible, easy-to-install brake controller that leverages modern smartphone technology, especially for trailers with 1 or 2 axles.
