Abstract
The invention covers a brake-booster of the partial vacuum type comprising a direct braking control mechanism (hill-holder or traction control). In order to implement these functions, the piston (20, 22) of the booster is "double" through a partition (52) which is attached securely to the piston and defines with the piston a third chamber (50). This chamber is connected by a flexible pipe (66) and a double valve (72) either to partial vacuum (78) or to atmospheric pressure (76).
