My first time changing brakes on XC60, discovered the electronic parking brake feature and the inability to reverse the pistons with a C clamp. With the calipers off I hit the parking brake lever in the car and they made noise but did not go in far enough. After searching on line I learned how to remove the electronic parking brake motor off the caliper and manually rewind the motor and the pistons retracted after that. I put it all back together and now I have the parking brake service light on and it says the parking brakes are not fully released. This is obviously a result of me hitting the parking brake lever with the calipers off, how can I reset the electronic parking brake? Or did I do something catastrophic to the motor?
