Lowly draw specialists Lancaster City snatched a 2-2 result at Hove Edge with a goal three minutes into added time.
It was a blow for Paul Quinn’s sixth-placed side who had led throughout the second half.
Ryan Hall opened the scoring for the hosts on 14 minutes, twisting and turning in the penalty area and firing into the roof of the net.
The lead was shortlived, Ryan Winder scoring from the penalty spot four minutes later.
However, Adam Wilson struck for Brighouse two minutes before the break, his effort from a low, driven corner taking a deflection before going in.
It was then stalemate before Aaron Taylor’s late, late equaliser for the visitors.
Brighouse are away to fourth-placed Spennymoor Town, who drew 1-1 at Farsley Celtic yesterday, on Tuesday.
