Bradford emerged on top after a stormy clash with Brentford which saw each side have a player sent off.
The visitors took the lead when new signing Zema Abbey side-footed home after a clever Dean Windass pass.
But Abbey then turned villain in a clash with Brentford's Deon Burton which ended with both being sent off.
Danny Forest doubled the visitors' lead after the break with a drive, before Brentford's Alex Rhodes pulled a goal back with a drive in the last minute.
