The proposed brake system eliminates breather bores and central valves in the working pistons of the master brake cylinder and establishes short-term pressure fluid connections between the supply reservoir and the working chambers when the brake is not applied by controlling replenishment valves and outlet valves. Therefore, connection of the supply reservoir to the working chambers of the working cylinder is constituted solely via electromagnetically controllable connections.

Hydraulic brake system

To improve the denseness of a reservoir telltale sounding device of a reservoir for a hydraulic brake system, while reducing the costs of manufacture and assembly, the plug portion comprises a first face and a second face which are respectively connected, in liquid-tight manner, to the housing of the reservoir telltale sounding device and the cover.

Reservoir for a hydraulic brake system

A process and device for producing a bearing eye or a transverse perforation in the clevis of the actuating rod of a brake power booster. The assembled brake power booster is inserted in a locking frame of the device, the clevis being retained at a cutting tool provided in a locking frame at a desired design distance of the clevis from the fixation flange of the booster casing. Upon insertion of the booster in the locking frame, the legs of the clevis are punched by a cutting punch so that in a single process step, a transverse punch hole or perforation to receive the pivot pin of the brake pedal is made maintaining a close tolerance to the desired design distance, i.e. independently of the specific position of mounting of the actuating rod and independent of the distance between the end of the clevis and the fixation flange of the booster casing.
