How to Select a Brake Control

The brake control is one of the most important inventions to come to the towing industry. It allows the driver to safely traverse the countryside, towing a large trailer load, without having to worry about being pushed down the side of a mountain by the weight of his or her trailer.

Inertia- and Time-Based Brake Controls

There are many different brake controls available on the market, but all can be classified into two activation types: inertia-based activation and time-based activation. CURT offer two of each type. Th Triflex and Reflex are inertia-activated controls, while the Discovery and the Venturer are time-activated controls. Knowing the difference between inertia-based and time-based brake controls is key for best meeting your customer's needs.

Inertia-based activation

Inertia-activated brake controls use accelerometers to measure the change in velocity of the tow vehicle when braking on multiple grades. An accelerometer is basically a highly accurate digital version of a pendulum that can measure inertia on more than one axis. The advantage of inertia-based activation is that once calibrated, the control can output the perfect amount of power needed to come to a smooth stop in any towing situation.

Time-based activation

Time-activated brake controls measure the amount of time the driver's foot is on the brake pedal and apply brake pressure to the trailer brakes accordingly. The longer the brake pedal is pressed, the stronger the signal will be that is sent to the trailer brakes. The advantage of time-based activation is that there is little calibration needed during the initial setup of the control.
