Hi and thanks for using 2CarPros. Com.
I recommend bleeding each wheel to confirm air hasn't gotten into the system. Just make sure to start with the right rear and work left front, left rear, right front. I have attached a picture which indicates the process.
Let me know if you have other questions. I hope this helps. Check out the diagrams (Below). Please let us know what happens.
