SQL 2012 :: Shrink Log In Synchronized DBs

I have two server A & B and I have always on high availability turned on SQL14.

I need to shrink the log on server A and it's fine if it also needs to shrink B.

My problem is that when I run my shrink command I get:

"cannot be shrunk until all secondaries have moved past the point where the log was added.."

I think I need to drop the High availability on the servers and then run this:

USE iTest2_Claims;
GO
ALTER DATABASE iTest2_Claims
SET RECOVERY SIMPLE;
GO
DBCC SHRINKFILE (iTest2_Claims_Log, 10);
GO
ALTER DATABASE iTest2_Claims
SET RECOVERY FULL;
GO

If the only way to shrink my log file is to drop high availibity how do I do that in script? and how risky is it that the high availaibity will not re-connect?
