More troubles with new master cylinder

I had bought the adjustable push rod from Cass as well as master. When I installed the adjustable push rod I had it extended too far not letting the brakes release. Your push rod may not be backing off and not allowing the brakes to release.
I am running my original push rod. So you are saying I may need to order the adjustable one from Dr. Diff? Thanks for the quick reply by the way.
