Beg for a new pedal (5)
I believe the answer is:
plead
'beg' is the definition.
(thesaurus)
'a new pedal' is the wordplay.
'a new' indicates an anagram.
'pedal' with letters rearranged gives 'PLEAD'.
'for' acts as a link.
(Other definitions for plead that I've seen before include "Implore, entreat" , "Beg or petition" , "Sue" , "Supplicate" , "Appeal humbly (to)" .)
