There is 2 cables (wired) that connect to the e-brake handle usally under the center console or even under the rug. Check those cable to see they are connected. Also if they are you will have to adjust the e-brake. There nut on the long thread will adjust if it goes in it will tighten (vice vesra). If those cable are connected make sure that it did not snap under the car of even on the brake pads or cailper depending what you got. Hope I helped!!!
