The device consists of a piston (2) fixed to at least one tension spring (3,13) and moving in a cylinder (1) which is controlled by a valve (8) positioned on top of the cylinder (1). When compressed air enters the cylinder (1) the piston (2) is pushed down and returns to its position when the spring (3) is relieved. The brake fluid is sucked from the container (7) during this process. The coupling (5) can now be taken from the outlet of the container (7) and joined to the reservoir (12) in order to fill the same.
