Review of Hayes Brake Controller HA81792BB


Today, we'll be reviewing Part Number HA81792BB. This is the Hayes G2 Brake Boss Trailer Brake Controller with Mounting Sleeve for 1 to 4 Axles. This brake controller is going to activate your trailer brakes in proportion to your vehicle's braking action. That automatically adjusts the trailer's brakes based on deceleration of the tow vehicle, and it activates immediately, so there's no pausing like with time-delayed brake controllers. It also has automatic leveling. It has an internal sensor that detects deceleration even if controller is not mounted flat. You can position this anywhere from 35 degrees to a 90-degree angle in the vertical plane.

Here on the front, it features adjustable gain settings that let you determine the power output sent to the trailer's brakes. That way, you can set it to a higher output when towing in hilly terrain or with a fully loaded trailer, or you can back off the power when towing a lightweight or empty trailer. It also has 4 boost settings that let you adjust initial braking power and aggressiveness. Has the easy-to-use push buttons here on the front, as well as a large, easy-to-read LCD screen that's going to communicate the brake power output, your boost settings, and the error codes. It has a high-resolution screen, so it is going to be also glare-resistant. Again, it has the easily adjustable and accessible buttons that let you change your settings. This system also features built-in safeguards that are going to protect your vehicle and trailer when it comes to safety.

It has an audible alert that warns the driver about wiring, continuity problems. It also has a manual override that illuminates the brake lights on the tow vehicle and trailer. It has a current limiter that's going to protect the vehicle from shorts in the trailer wiring. It also features hazard flasher immunity that's going to prevent pulsing of the brakes when flashes are activated. That manual override is here on the bottom, and its just a nice, easy-grip slide system. This is made from a dependable solid-state construction. Its a pretty quick and easy installation.

You just plug this in. Hayes does offer vehicle-specific, brake control and adapters that are sold separately that can be used for certain applications to reduce installation time. It features this nice mounting sleeve that attaches to your tow vehicle's dashboard with a 3M tape that's already on there, so no drilling is required. It allows the brake controller to be easily removed for storage or for use in other vehicles. This is designed to be used with trailers with up to 4 axles or 8 brake assemblies. Its designed for use with electric or electric-over-hydraulic brakes. The dimensions.

This is going to give us a measurement of 3-1/4" in width, about 5" in length, and 1-1/4" in height. It also comes with an alcohol-prepped cloth. That way, you can clean off your service before you peel off the adhesive and mount this to your dash. That's going to do it for today's review of Part Number HA81792BB. This is the Hayes G2 Brake Boss Trailer Brake Controller. .
