Beschreibung
Zusammenfassung:	A device including a master cylinder driven by a control member, an enclosure for a pneumatic booster having a rear chamber separated from a front chamber by a piston, first and second balancing valve elements place the rear chamber in communication with the front chamber, first, second and third intake valve elements place the rear chamber in communication with a pneumatic pressure source, and a tubular support. The balancing valve elements are carried by a balancing part of the support and the pneumatic piston while the intake valve elements are carried by the first part of the control member, an intake part of the support and a second part of the control member. The first and second parts of the control member are connected through a spring arrangement for adjusting the relative axial position thereof as a function of the power of the force applied to the control member.
