Breaks in pieces (5)
I believe the answer is:
parts
I believe this clue is a double definition.
'breaks' is the first definition.
(I know this)
'pieces' is the second definition.

'in' is the link.
(Other definitions for parts that I've seen before include "bits" , "Areas" , "Strap (anag.)" , "Components of strap" , "Leaves" .)
