This disclosure describes a brake-fluid conduit for conducting a brake fluid between a fluid pressure supply device and a wheel cylinder of a hydraulic disk brake system. The brake-fluid conduit comprises a tapered portion having a cross-section that is largest at an end of the tapered portion facing the wheel cylinder and that narrows towards an end of the tapered portion facing away from the wheel cylinder.

An apparatus includes a first electrical component, a second electrical component, and a brake line. At least part of an electrical connection between the first electrical component and the second electrical component is defined by the brake line. The electrical connection may be a secondary electrical connection for rerouting an electrical path. The brake line may include first and second tubular conductive structures for defining first and second electrical connections. A repeater may be used to retransmit a data signal along the brake line. A nonconductive layer may be disposed on a tubular conductive structure of the brake line. A controller may switch operation of the brake line between an electrical power transmission mode and a data signal transmission mode. A controller may be operable determine a connected state or a disconnected state of the brake using the electrical connection.

A tube fitting includes: a zinc-based plated layer; and a resin coating layer that is positioned at an outermost surface at an outer side of the zinc-based plated layer and includes a polyethylene substance, a lubricant, and solid particles. When a fitting average plating thickness t relating to the thickness of the zinc-based plated layer is defined, 2.1<t<19.7 is true.

A vehicle brake device component, which has a first connection element including a sealing edge and a second connection element including a sealing surface, the sealing edge being placed tightly against the sealing surface in an initial position prior to a temperature change, and at least one of the two connection elements undergoes a change in size during the temperature change, in the process of which the sealing edge is displaced into an end position relative to the sealing surface, the sealing surface being developed in such a way that the sealing edge is placed tightly against it also in the end position.

Brake fluid reservoir valve for installation in the reservoir's outlet tube. It includes an outer sleeve fixed in the reservoir tube and equipped with an outer stop and a hollow piston housed in the sleeve. The top of the piston is closed and bordered by a groove accommodating an o-ring seal that rests upon the upper edge of the sleeve whenever the piston enters the sleeve. The piston has windows beneath the groove communicating with the interior of the piston and lugs near its lower extremity. Openings are provided in the extension of the piston beneath the lugs. A compression spring is inserted between the piston and the outer sleeve, between the stop and the lugs.

For the purpose of redundancy, ports are provided for a separate power brake pressure unit on a hydraulic block of a hydraulic unit of a slip control system of a hydraulic vehicle power braking system. The ports are attached as cylindrical collars to the hydraulic block by friction welding.
