Good morning, inorder to accurately diagnosis this issue it will require a special tester to check the pressures:

Your local dodge dealer would have this tool and they are who I would recommend having check it further due to having the correct tools to check it accurately with out throwing parts at it. The foaming may be air in the lines. TO be sure start vehicle and cycle the p/s as much as possible and apply the brakes as well. Then turn engine off and remove p/s cap. Allow the fluid to become free of air bubbles and then repeat until the air is gone and the p/s and brakes work normally. If still not working then having the pressure checked would be your next step. Let me know if I can help you further.
