Product Description

Digital, proportional, accelerometer brake controller designed for use on single, tandem, tri or quad braking trailers. Digital, diagnostic read-out. No level adjustment required.

The Endeavor is the top of the line in brake controllers. This controller has the ability to sense deceleration of the tow vehicle, which provides premium braking. This controller is equipped with a digital display allowing you to select percent of power, voltage, or current. The Endeavor is equipped with a microprocessor allowing it to save all your settings. The smart controller includes several diagnostic tools to help you in your braking needs.

Mounting Angle and Mounting Direction

Mounting angles between 35 and + 90 degrees can be accommodated by the controller. The unit must, however, be installed so that it is parallel with the travel of the tow vehicle and trailer. Use the included reversible slotted mounting bracket and machine screws and fasteners to mount your controller with the back of the controller toward the front of the vehicle. Always be sure to mount in a location which allows the driver to easily apply the manual override and to see the red indicator light.

Automatic Operation with Digital Display and Standby Mode

During braking, the Endeavor senses deceleration of the tow vehicle. An internal sensor measures the amount of deceleration and sends a proportional amount of power to the trailer brakes. The maximum braking supplied depends on the set up of the controller. The digital display will indicate the amount of power being sent to the trailer brakes. Once the brake pedal is released, the unit will return to stand by mode. While standing by, the controller will display the currently selected mode of display (% power, voltage, or current).

Maximum Power with Automatic and Manual Settings

Under automatic braking (via brake pedal), the maximum power is the percent of available power that is sent to the trailer brakes. Under manual override (via manual slide lever), the maximum power is the percent available power that is sent to the trailer brakes when the manual slide lever is moved all the way to the left. Choose Automatic Maximum Power settings, or use the Manual Override slide lever to apply the trailer brakes independently of the tow vehicle brakes or to override the automatic trailer brakes when less braking is required. The Manual Override slide lever can be used for emergency stopping or for control of excessive trailer sway. The tow vehicle and trailer brake stoplights will still illuminate during the manual lever activation.
