Vehicle in this way met by chap's brother? (10)

I believe the answer is:

carthusian

'brother?' is the definition.
(Carthusian monk)

'vehicle in this way met by chap's' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle).
'in this way' becomes 'thus' (synonyms).
'met by' is a charade indicator (letters next to each other).
'chap' becomes 'Ian' (man's name).
'car'+'thus'+'ian'='CARTHUSIAN'

I've seen this clue in The Times.
