10 Best Brake Controllers 2025 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 8508220 Brake-EVN Proportional Electric Trailer Brake Controller offers a reliable solution for those towing trailers with 1-4 axles. One of its main strengths is its proportional braking system, which adjusts the trailer's brake intensity based on the tow vehicle's braking, thanks to an internal inertia sensor. This ensures smoother and more controlled stops, enhancing safety.

It is versatile, being compatible with a wide range of vehicles, including Ford, GM, Chevy, Dodge, RAM, Toyota, and Jeep, and works with trailers having 2, 4, 6, or 8 brakes. The Plug & Play installation feature makes it user-friendly, especially for those who may not be very experienced with vehicle modifications. The removable electrical connector also adds to its convenience, enabling easy uninstallation when needed.

The LED display is clear and provides real-time diagnostics and alerts, which is beneficial for maintaining awareness of the braking system's status. Additionally, the ability to manually apply the trailer brakes using a control lever adds an extra layer of control in emergency situations. On the downside, the need for a vehicle-specific Tekonsha Plug & Play wiring harness, which is sold separately, could be seen as an extra cost and a potential hassle for some users. Furthermore, while the product's dimensions and weight make it compact and lightweight, the 1x1x1 inch dimension listed might be inaccurate and potentially misleading.

The Tekonsha 8507120 Brakeman IV is a time-delay brake controller designed for trailers with one to four axles, making it a solid choice for light-duty towing. Its main strength lies in its simple, consistent braking power that increases gradually, which is easy to use for those new to towing. Installation is straightforward thanks to its plug-and-play design, though you will need to buy the appropriate wiring harness separately for your vehicle. The controller fits a wide range of popular trucks and SUVs including Ford, GM, Chevy, Dodge, RAM, Toyota, and Jeep.

The digital display is clear and practical, showing settings and trailer connection status, which helps keep things safe and under control. It also allows manual braking if you want to apply trailer brakes independently, adding flexibility. However, because it uses a time-based system, it may not respond as precisely as proportional controllers that adjust braking power based on how hard you press your vehicle’s brakes. This means it’s best suited for lighter trailers rather than heavy loads that need more sensitive control.

The Brakeman IV is compact and can be mounted above or below the dash in any direction, which helps with ease of use while driving. With a high customer rating and solid build quality, this controller offers a reliable option for everyday towing needs, particularly for those seeking simplicity and dependability without extra complexity.
