Dundalk maintained their 100pc away record as Bray extended a different sort of sequence at the Carlisle Grounds.
Having taken maximum points on the road from four previous games, Pat Hoban's header early in the second half gave Dundalk another victory and condemned the Wicklow outfit fall to a seventh successive loss, which sees them rooted to the bottom of the table.
After a lacklustre first period, Dundalk boss Stephen Kenny made a double change at the interval by bringing on Darren Meehan and Kurtis Byrne.
And it did the trick in the 51st minute, when the visitors made the breakthrough. Meehan swung in a corner from the left flank and Hoban rose in a crowded six-yard area to steer home a downward header.
The Seagulls went close to drawing level late on through sub Ismahil Akinade and Dave Webster, but Dundalk held out.
