sorry for slow reply guys been out seeing the sun etc etc....
Went to portobelo road bike workshop today to get the rear sproket tightened and the lockring changed... Aparently the lockring threading was worn down so wasnt staying tight...
So looks like problem is fixed now with the rear sproket...
as i am new to this i have left the rear brake on and i am using shimano spds so now safe as possible!!!
