Braking device for a motor vehicle

A braking device for a motor vehicle, comprising a first brake circuit (10), which includes a master cylinder (11) controlled by a brake pedal (12), the outlets (14, 15) of said master cylinder being connected to wheel brakes (18) via connection means (21, 23, 25) controlled by a programmed computer (C), a second brake circuit (20), which includes at least one pump (27) supplied from the master cylinder (11) in order to supply the wheel brakes (18) under control of the computer (C), and pedal travel simulation means (40) associated with the first brake circuit (10) and allowing displacement of the pedal (12) when the aforementioned connection means (21) are closed, the travel simulation means (40) comprising a solenoid valve (41) which is mounted in a pipe (42) containing a hydraulic fluid and connected to a hydraulic fluid storage chamber (43), said solenoid valve being controlled by the computer (C) so as to open in order to allow the hydraulic fluid to flow toward said storage chamber when the brake pedal is actuated by the driver, characterized in that the pipe (42) that includes the solenoid valve (41) is connected to another pipe (44) in which hydraulic fluid is displaced by a part (45) of a control rod provided between the brake pedal (12) and another part (46) of the control rod associated with the master cylinder (11) or with a pneumatic brake booster.
