My buddy has a 2007 Heretage Softtail and asked me to change the rear pads on it. Change went without a hitch. First time to do a softtail and had no manual. After finishing brakes worked just fine but the brake lights wouldn't work except when the front brake lever was applied. Could I have inadvertently done something? Where is brake light switch? I had to add a little fluid and bleed a little air but like I said they work fine.
