A brake system with a wheel brake has a fluid reservoir and a valve assembly in fluid communication with the reservoir via a first conduit. The valve assembly is in fluid communication with the wheel brake via a second conduit. The valve assembly includes a bypass valve which only permits fluid flow from the first conduit to the second conduit when the fluid pressure within the first conduit is above a predetermined pressure level above atmospheric pressure. The valve assembly further includes a check valve in a parallel path arrangement relative to the bypass valve such that the check valve permits fluid flow from the second conduit to the first conduit, and prevents fluid flow from the first conduit to the second conduit. The brake system further includes a first source of pressurized fluid providing fluid pressure for actuating the wheel brake, wherein the first source of pressurized fluid is selectively in fluid communication with the second conduit.

A pressure sensor for a brake booster includes a housing that receives a pressure sensor element and which has a first fluid connection, via which the pressure sensor can be connected to the brake booster. The housing has a second fluid connection with a receiving opening which at least partly receives a flow valve and a connection socket for a vacuum pump, wherein the flow valve releases the flow of fluid in the direction of the vacuum pump and blocks the flow of fluid in the opposite direction. The flow valve is designed as a membrane insert and is inserted into the receiving opening.

A saddle-riding-type vehicle cable support structure is a cable support structure configured to support a first cable and a second cable that are joined to a side part of a wheel, the cable support structure including: a joint section provided on a middle of the first cable and which is fixed to a vehicle body; and a second cable support member attached to the joint section and which supports the second cable.

A normally closed port valve seals a hydraulic hose connection port of a hydraulic bicycle component. Connection of an end of a hydraulic hose assembly to the port opens the valve, placing the assembly's hydraulic fluid chamber in fluid communication with the interior of the hose assembly. A hydraulic cylinder of the assembly is in fluid communication with the chamber. A spring may be used to bias the valve to a closed condition.

A method for verifying the operation of braking means of at least one vehicle, in particular a railway vehicle, is described, comprising the steps of: a) imposing a braking force on at least one wheel of the at least one axle of the at least one vehicle; b) towing the at least one vehicle according to a non-zero and constant forward speed; c) measuring on a rail at least one friction force which is a function of a braking force; d) comparing the at least one measured friction force with a predetermined minimum force value; e) determining that the braking means associated with the at least one wheel whose friction force is lower than the predetermined minimum force value are malfunctioning. Also described are a system for measuring a friction force and a system for verifying the operation of braking means of at least one vehicle.
