Knaresborough Town were held to a goalless draw at Manse Lane by a determined Campion side, well worthy of their share of the spoils.
Paul Stansfield’s men remain top of the NCEL Division One standings, however, as second-placed Eccleshill United suffered a 3-2 home defeat to Selby Town.
Devonte Morton had a great early chance for Campion, but his lob was just about saved by Boro gloveman Jack Rushworth.
At the other end, Steve Bromley first headed over from a Dan Thirkell free-kick and then controlled well and turned nicely, only to fire over the crossbar.
Bromley then had a try from long range, but visiting goalkeeper Daniel Armitage saved comfortably.
Ben Cohen was the next to go close for the hosts when his shot hit the side-netting and then Rob Youhill cut in from the left only to see Armitage gather his strike.
Campion grew frustrated with the referee and his reaction was to show a sequence of yellow cards to away players.
Chances were few and far between after half-time but Morton had another great opportunity to give the visitors the lead, only to see his weak effort fail to beat Rushworth in the home goal.
The final few minutes did produce one scramble of note in the Campion goalmouth as a corner was not cleared and both Will Lenehan and Dan Thirkell saw efforts blocked by last-ditch challenges.
The Bradford outfit managed to hold out, however, making it through to the final whistle with their clean-sheet intact and boosting their hopes of climbing into the play-off positions.
Boro’s lead at the summit is extended slightly to two points, but crucially they still hold two games in hand over nearest challengers, Eccleshill.
Next up for Stansfield and his troops is a trip to 16th-placed East Yorkshire Carnegie.
