  • The TriFlex™ proportion-based brake controller features a compact size, a digital display and the ability to manage up to eight brakes at a time. The feature that sets the TriFlex™ apart from many others is its triple-axis motion-sensing accelerometer. This integrated circuit component allows the TriFlex™ to detect every motion of your vehicle and trailer with exact precision and to then apply the perfect amount of braking power for every situation. The TriFlex™ also automatically adjusts brake output when going up or down a hill and is compatible with anti-lock brakes and cruise control.

    A brake controller should be mounted somewhere on the dash of your vehicle, and we recommend putting it below the steering wheel, either on the right or left side of the steering column. This way the control will not block your view when driving, but it will remain accessible and visible when adjustment is needed.
