When activating the brakes of your vehicle with the Curt Echo part # C51180 the vehicle and trailer will need to be in motion for the sensor of the controller to feel the deceleration and apply the brakes proportionately. If you are applying them at a stop they controller won't do much. Also if the brakes are brand new they do need to be adjusted initially so that there's the proper tightness to activate them.

To see how to manually adjust trailer brake assemblies check out the video I attached, fast-forward to the 4:35 mark of the video I attached a link to on this page.
