Do your brake lights work? I know it sounds dumb but you have to start there. you might have a bad connection in the pigtail between the brake switch and the controller. The brake switch sends the signal to the controller, the contoller amplifies it and sends the appropiate voltage to the brakes based off inertia. If you put a voltmeter on the wire that feeds the brakes you will see the voltage change as you push the lever. good luck
