Take apart broken tin medals (9)
I believe the answer is:
dismantle
'take apart' is the definition.
(I know that take apart can be written as dismantle)
'broken tin medals' is the wordplay.
'broken' indicates an anagram.
'tin'+'medals'='tinmedals'
'tinmedals' with letters rearranged gives 'DISMANTLE'.
(Other definitions for dismantle that I've seen before include "To demolish" , "Take apart" , "strike" , "Unrig" , "Take to bits" .)
