Abstract
In a brake booster comprising a control rod (30) actuating a booster mechanism (34, 20a, 28a) by way of a plunger (28), in order to exert a boosting force on a piston (20) acting on a push rod (46) via a reaction disc (48) made of a deformable material, an adjustable prestress is applied to the latter. This result can be obtained particularly by way of a cover (50) capping a plate (46b), formed at the rear end of the push rod, and the reaction disc (48). The prestress thus applied to the disc makes it possible to adjust the play existing between the latter and the front end of the plunger (28) and consequently the jump of the booster.
