An actuator assembly for a vehicle brake is described. It comprises a carrier assembly () on which an activating carriage () for a brake lining is guided linearly. Moreover, an electric motor fastened to the carrier assembly () is provided which is coupled drivingly to the activating carriage via a gear unit and a spindle drive such that the activating carriage can be displaced selectively between a retracted position and an extended position. In addition, the actuator assembly comprises a locking assembly () for selectively immobilizing in rotation an output shaft () of the electric motor. The locking assembly () here comprises a locking lever () which at a first end () is mounted rotatably on the carrier assembly () and at a second opposite end () is coupled to a locking actuator (). A locking tooth () is moreover positioned between the first end () and the second end (). A method for activating an actuator assembly for a vehicle brake is furthermore presented.

The disclosure relates to a main brake cylinder arrangement for a motor vehicle brake system, comprising: at least one piston, which can be displaced along a displacement axis (V) and, together with a housing arrangement, delimits a pressure chamber; a force input member, which is displaceable according to a brake pedal actuation and is coupled or can be coupled to the piston for common displacement; an elongated position encoder element, which is displaceable according to an actuation of the force input member; a detection unit, which is designed to detect a displacement of the position encoder element; and a receiving region, which is designed to receive the position encoder element at least in part. The ends of the position encoder element are each arranged in a different housing region (F, S), which is arranged in a fluid path between the first and second housing region (F, S).

A piston pump housing for a hydraulic pressure generator in a vehicle brake system includes a housing, in which a bore for receiving an eccentric shaft is formed. In the housing at least six cylinders for receiving one pump piston each are further provided. The cylinders are disposed in pairs in three or more mutually spaced-apart planes and open out in each case into the receiving bore for the eccentric shaft. According to a possible realization, in a two-circuit vehicle brake system at least three cylinders are associated with each brake circuit to increase the operating comfort. To reduce wear, each of the provided eccentrics interacts with only two pump pistons.
