The system has an electric brake booster (200) with a rack drive (260) connected to an actuator piston to act on a tandem master cylinder (100). The piston has a flange ring forming a housing with a circular shoulder constituting a support surface for a re...

A moving piston (24) has a front face (26) that acts on primary piston (30) of a master cylinder (14) via a reaction disk (28). A feeler (44) at the front face of the moving piston has at least one stud which engages the reaction disk to provide for propor...

The servomotor has a shock absorbing unit (68) absorbing relative movement and oscillation between a control shaft (33) and a pneumatic piston (8). The shock absorbing unit comprises an annular joint (72) having a high friction coefficient and mounted in a...

A booster includes an output shaft (36) a base (36A) of which comprises a rod member (36B), and a holder (43) having a bottom (43A), a stop (42) being formed separately from the holder, the holder having a reduced diameter portion (43B), in which an outer ...

The braking amplifier with double ratio amplification comprises a thrust set (71) comprising a reaction rod (82) connected to the brake master cylinder. The rod can be axially displaced under the control of a plunger (22) between a first braking state corr...

This brake force amplifier comprising a piston (6) actuated by a pressure differential between two chambers, a plunger (11) mounted axially displaceable within this piston (6) between positions controlling the evolution of this pressure differential by mea...
