Bradford picked up their second away win of the season at Dagenham.
The visitors took the lead in the 19th minute when Peter Thorne headed in after being unmarked at the back post.
Dagenham's Paul Benson had a volley ruled out for offside and the home side then had Solomon Taiwo shown a red card for a challenge on Darren Williams.
David Wetherall headed in a second for the Bantams before Paul Benson got a goal back but Nicky Law struck twice late on to give Bradford victory.
