Two tries from Alexis Palisson helped Brive beat Sale Sharks 18-9 in the Amlin Challenge Cup on Saturday.
In Pool Two's other match on Saturday, Petrarca clinched their first victory in the competition with a 37-10 success over Spanish side Cetransa El Salvador.
In freezing conditions in Brive, all the points came in the first half, as both sides struggled to retain the ball.
International winger Palisson took advantage of two major passing errors from the Sharks to run in both his side's tries. Man of the Match Julien Caminati added a conversion and two penalties.
Three penalties from Sharks' skipper Nick Macleod were scant consolation for the English visitors.
Tries: Palisson 2
Pens: Caminati 2
Pens: MacLeod 3
