Travelling rep due's broken down (6)
I believe the answer is:
pureed
'broken down' is the definition.
Both the answer and definition are past participle verbs.
Maybe you can see an association between them that I don't see?
'travelling rep due's' is the wordplay.
'travelling' indicates an anagram.
'rep'+'due'='repdue'
'repdue' is an anagram of 'PUREED'.
Can you help me to learn more?
(Other definitions for pureed that I've seen before include "Pulped like fruit or veg" , "In cookery, reduced to a smooth pulp" , "Made into pulp, fruit or vegetables" , "Pulped, say fruit or vegetables" , "Liquidised" .)
