recoil brake

The last steps were to connect the recoil brakes' pistons to the barrel, fill and test the recoil brake and recuperator, and install the roller race.

The French Army had to wait until early 1917 to receive in numbers fast firing heavy artillery equipped with hydraulic recoil brakes (e.g. the 155 mm Schneider howitzer and the long-range Canon de 155mm GPF).

In the meantime it had to do with a total of about four thousand de Bange 90 mm, 120 mm and 155 mm field and converted fortress guns, all without recoil brakes, that were effective but inferior in rate of fire to the more modern German heavy artillery.
