When an element of the electro-hydraulic brake circuit () is malfunctioning, a master cylinder () can brake the vehicle. A brake actuation simulator () is then disconnected from the master cylinder () by means of an O-ring gasket () after the gasket has been compressed between a groove () in a secondary piston () and a bore () in the master cylinder. In order to prevent the gasket from being extruded from the groove during brake release (or brake pedal release) resulting from sudden braking, the invention makes provision for a pressure relief duct () to be provided inside the secondary piston. Extra pressure can then be discharged during brake release (or brake pedal release) through the brake release duct () from the inside of the chamber () of the simulator towards the primary chamber () of the master cylinder.

Electro-hydraulic brake circuit for a vehicle

The servomotor, of the type incorporating an abutment component (7, 70) which is mounted on the input rod (6) and which cooperates in bearing, in the rest position of the servomotor, against a stop structure (9, 12) which is firmly fixed to the casing, incorporates in the stop structure an electrical contact mechanism (13, 15) which is capable of being actuated by the abutment component (7, 70) and which advantageously incorporates and actuating portion (17) which is interposed between the abutment component (7, 70) and an internal bearing surface (20) of an end collar portion (12) of the stop structure which carries the fixed electrical contacts (13).
