Fix ends of rake with brace (6)
I believe the answer is:
repair
'fix' is the definition.
('repair' can be a synonym of 'fix')
'ends of rake with brace' is the wordplay.
'ends of' suggests removing the centre.
'with' is a charade indicator (letters next to each other).
'brace' becomes 'pair' ('pair' can be a synonym of 'brace'**).
'rake' with its middle taken out is 're'.
're'+'pair'='REPAIR'
(Other definitions for repair that I've seen before include "retire" , "Correct" , "Proceed - restore" , "Restore to good order" , "Restore, set right" .)
