Matt Lee's reports from Cressing Road...
Scott Fenwick and a late Trialist effort almost snatched a victory but ultimately it was another performance of endeavour with no reward as the Clarets were left frustrated.
Rhys Murphy carved an early chance when he rounded two defenders, but his curling effort went wide of the post.
The Clarets came close once again midway through the first half when Jai Reason's corner was pulled back towards Amos Nasha, although the midfielder's shot flew wide.
Reason's carefully threaded pass almost picked out Murphy's run through-on-goal, although the flag was raised for offside.
Braintree Town's first clear-cut effort on goal finally came on 39 minutes. Summer recruit Lyle Della-Verde cut inside on the left-wing and flashed a shot across goal, but it went narrowly wide of the far post. Moments later Marcel Barrington came close, but his teasing cross was not converted.
Mahrez Bettache had only one thing on his mind when he looked to take advantage of Matt Young's mis-clearance, although the Braintree midfielder was unable to open the scoring as he curled wide early in the second half.
Tom Wraight's excellent cross to pick out Young provided hope of a City opener following a period of dominance from the hosts, although shot-stopper Ashlee Jones collided with Young to deny the Chelmsford man from scoring.
Braintree had weak claims for a penalty waved away when Christian Frimpong went down inside the area. The hosts played on but Mustafa Tiryaki's effort was saved well by Worner.
The Clarets came close late in the second half when a Trialist forced a fingertip save from Jones after 87 minutes before Fenwick had a close-range effort scrambled away, but it was another performance with no reward as City finished their preparations for the League campaign.
Clarets XI: Worner, Young, Wraight, Porter, Swaine, Omozusi, Anderson, Church, Murphy, Nasha, Reason.
