There's a 5mm hex bolt that you need to loosen. It's right in the lever, directly behind the cable stop. You'll need to loosen the cable at the brake caliper to get enough slack to get the wrench in there. If you're just switching bars and not replacing the cable and housing, don't pull the cable out, just leave it loose.
