How to change MySql Master-Master Replication to Master-Slave Replication

I currently have MySql Master-Master replication set-up with Read_only on Master2. There were lot of sync issues so I’ve stopped replication from Master2 to Master1 by stopping the Slave in Master1. Master1 is currently replicating to Master2 with no issues. Is this enough or is there another best way to revert to Master-Slave replication. Should I run RESET SLAVE on Master1 to completely stop Replication from Master2 to Master1.
