Brook twice battled back from behind to claim a vital two points in their promotion bid, beating Coventry Bears 28-20.
The Bears took an early lead when Alex Brown burrowed his way over the line.
Midway through the first half though the home side levelled when good work by Joe Bate and Danny Fairhurst paved the way for Jon Glover to crash over.
Five minutes before the interval Coventry regained the lead as a break by full-back Duncan Barrett from inside his own half ended with Stephen Coleman going over wide out for an unconverted try.
But Brook again bounced back when Coventry spilled the ball from the re-start giving the homesters possession from which winger Danny Beckett’s run set up the position for Danny Fairhurst to step past two defenders for a superb solo try.
After the break the Brook pack, led by Sean Richardson and Joe Bate, began to take control and the home side stretched their advantage with two tries in the opening 12 minutes by Jack Parker and Danny Fairhurst.
And they looked to have put the game to bed when good work by Richardson and Parker laid the foundations for Dave Scott to send Danny Beckett over in the corner, with Parkinson’s touchline conversion making it 28-10.
Coventry pulled back some points with two tries later on in the game.
