BRADFORD sealed a seventh straight victory - but a nasty late arm injury to Danny Brough which could keep the veteran halfback out for more than two months dampened the celebrations.
While John Kear’s side remained third, hard-working Newcastle are still in the bottom three with one win and a draw.
The Bulls ran in five tries, four in a forceful second-half display, resulting in a final scoreline which left resilient Thunder with insufficient credit.
It was all square at half-time, but Anthony Walker led a stirring display after the break as Bradford finally managed to punch holes in a hitherto sound Newcastle defence.
