Two goals in six second-half minutes from Marcel Licka and Romain Poyet earned Brest the result which moves them two points clear of Rennes, whose match at Marseille was postponed because of a waterlogged pitch.
St Etienne drop down a spot to fourth, level on points with Marseille and Toulouse, who were held to a 1-1 draw at home by spirited Lens.
The hosts held an early advantage thanks to Paulo Machado's penalty, but Lens dug deep and Alaeddine Yahia scored the goal which moved them out of the bottom two at the expense of Monaco, who take on Bordeaux on Sunday.
Lyon continued their recovery from a poor start to the season with a 2-1 victory over Sochaux. Michel Bastos fired Les Gones in front on the half-hour before Brown Ideye levelled matters.
However, substitute Alexandre Lacazette grabbed what proved to be the winner as Lyon climbed to eighth.
Auxerre also gave their league campaign a welcome lift by beating Nice 2-0, courtesy of goals from Valter Birsa and Benoit Pedretti.
Nancy moved level on points with Caen after winning their mid-table clash 3-2. A Youssouf Hadji penalty and own goal from Gregory Tafforeau gave Nancy the lead after Youssef El Arabi had put the home side in front.
Kandia Traore then levelled for Caen, but namesake Bakaye Traore fired Nancy in front for good after 70 minutes.
Arles continue to prop up the standings after losing 2-0 at Lorient. Kevin Gameiro and Lynel Kitambala scored the goals which ensure Arles are still without a win this season.
