In a method for controlling a hydraulic braking system, in the event of a failure of a primary brake actuator system, a secondary brake actuator system is activated.

A vehicle brake system and method for increasing the brake pressure in a first wheel brake cylinder and for limiting the brake pressure in a second wheel brake cylinder of a vehicle brake system. The method includes increasing a first brake pressure in the first wheel brake cylinder by controlling/holding a wheel inlet valve in its open state and controlling/holding a first wheel outlet valve in its closed state, and limiting an increase of a second brake pressure in the second wheel brake cylinder during the transfer of brake fluid into the first wheel brake cylinder by controlling/holding a second wheel inlet valve in its closed state and controlling a second wheel outlet valve into its open state. The second wheel outlet valve is controlled with a pulse width-modulated signal so that during the transfer of brake fluid, the second wheel outlet valve is permanently in its open state.

A hydraulic block for brake control of an automotive hydraulic braking system, including a main brake cylinder bore. A permanent magnet is connected to the main brake cylinder piston via a rod, so that the permanent magnet moves together with the main brake cylinder piston. A Hall sensor with which a position and/or a stroke of the main brake cylinder piston is measurable is situated in a signal range of the permanent magnet in a sensor bore in the hydraulic block transversely to the rod.

A non-return valve for a vehicle hydraulic-power brake system. The non-return valve has a valve-seat part in the form of an apertured disk, onto which is pressed a valve cage in which a valve ball is disposed as shut-off member and a helical compression spring is disposed as valve spring. A bowl-shaped filter is secured in a depression in the valve-seat part opposite the valve cage.

A brake system for actuating front and rear wheel brakes includes a reservoir and a master cylinder operable during a manual push-through mode by actuation of a brake pedal to generate brake actuating pressure at a first output for hydraulically actuating the pair of front wheel brakes. A power transmission unit is configured for selectively providing pressurized hydraulic fluid for actuating the pair of front wheel brakes and the pair of rear wheel brakes during a braking event. First and second two-position three-way valves are provided. Each three-way valve is hydraulically connected with the master cylinder, the power transmission unit, and a selected one of the front wheel brakes. Each of the first and second three-way valves selectively controls hydraulic fluid flow from a chosen one of the master cylinder and the power transmission unit to the selected one of the pair of front wheel brakes.
