How do I break a master-master back to master-slave ?

q: How do I break a master-master back to master-slave ?

I have a DB that used to be a master-master setup
I now want it to be a master-slave configuration again
but it thinks it's still a slave to another db !!!
How do I break this ?
What parameter in the my.cnf file makes it think it's a slave to another DB?

I remove this parameters and restart mysql
- will it then stop thinking it is a slave?

relay-log = /var/log/mysql/relay-logs/mysqld-relay-bin.log
relay-log-index = /var/log/mysql/relay-logs/mysqld-relay-bin.index
relay-log-info-file = /var/log/mysql/relay-logs/relay-log.info
relay-log-purge = 1 #1=true , 0=false
auto_increment_increment = 10
auto_increment_offset = 7

===========================================

If I do > Show slave status ;
it gives the hole list of slave info
and slave running is : NO
but
I want it to give nothing ie empty results

===================================================

maatkit: mk-slave-info: list it as a slave !!!
