Brest continue to search for their first win of the Ligue 1 season after earning their eighth draw in 10 matches against Caen.
The hosts went ahead before the interval through Bruno Grougi, but Thomas Heaurtaux levelled six minutes from time to once more deny Brest a three-point haul.
They remain unbeaten at home, though, and above the bottom three despite being without a win.
Caen had the first chance of the match after eight minutes with Romain Hamouma teeing up Kandia Traore with the perfect cross, but the striker put his header narrowly wide.
Brest responded with a free-kick four minutes later, which was taken by Grougi but comfortably saved by Alexis Thebaux in the Caen goal.
Both sides continued to create openings as the half wore on but the home side eventually made the breakthrough a minute before the interval.
They were awarded another free-kick on the edge of the area, and this time Grougi made no mistake with a superb strike beyond Thebaux into the top left corner.
Nicolas Seube tried to get Caen back on level terms early in the second half but fired a volley wide of the target.
Grougi's cross almost set up Nolan Roux for a second Brest goal after 60 minutes, but the youngster's header sailed over the crossbar.
Caen began to push forward in numbers after that, and gave Brest a scare with a shot from Pierre-Alain Frau which goalkeeper Steeve Elana needed two attempts to gather.
But the visitors' pressure finally paid off in the final six minutes, with Heaurtaux meeting a delivery from Benjamin Nivet and poking the ball through Elana's legs into the back of the net.
