Warren Mann (24) said his colleagues at Painswick Fire Station in Gloucestershire nicknamed him 'Gunga Din' after the Kipling poem, ignored him, and left him in the station to make the tea.
The Bristol tribunal heard that his confidence and that of his family was destroyed by three years of abuse.
Mr Mann said that as soon as he joined as a part-time fireman in September 1993 he suffered racist abuse. It became worse after he made a formal complaint.
The tribunal ruled that officers had made racist comments in Mr Mann's presence and had shown a 'patronising and insensitive attitude'.
The damages will be decided later.
