Bromley struck three times in the second half to secure a 3-0 victory at in-form Gateshead.
The hosts were hoping to make it seven consecutive league wins but fell apart after half-time.
The Tynesiders went behind after 55 minutes when Harry Forster’s well-placed cross found Corey Whitely who finished the job at the back post.
Ryan Stirk’s debut goal for Bromley was the result of some fine build-up play that saw Michael Cheek latch on to Louis Dennis’ ball over the top to set up the 22-year-old before Dennis netted one of his own to seal the win.
