2010 Nitro had a contaminated brake system removed all components with rubber in them. Calipers, Hoses, Master ABS control Module and its Brain. Finished cleaning it and prepping it bled the system per the proper sequence 1234 junction 5678. ABS ESC Traction and Brake lights are now on and wont go off tried test drive seems to brake ok but RR seems to get a locked up feeling but it does release... any ideas? Does the brain of the ABS control module have to be programmes by dealer? Do I just throw the old one back in?
