Electric parking brake

[mike64220]

Hello. I have a 2008 S80. I replaced pads and rotors in the rear a few weeks ago. Yesterday the warning came up that parking brake is not fully released and is dinging while driving. I went and manually made sure the brakes were fully released and they are but the warning won't stop. Have unplugged battery to try resetting the message but no dice. Any ideas? Thanks in advance
