Beg for new pedal (5)
I believe the answer is:
plead
'beg' is the definition.
(I know that beg is a more specific form of plead)
'new pedal' is the wordplay.
'new' is an anagram indicator.
'pedal' is an anagram of 'PLEAD'.
'for' is the link.
(Other definitions for plead that I've seen before include "Implore, entreat" , "Claim; entreat" , "State whether one is guilty or not" , "Sue" , "Say one is guilty or not guilty" .)
