Abstract: The invention relates to a hydraulic assembly of a vehicle brake system with traction control. Hydraulic assemblies include a housing block, which is to be fitted with hydraulic components, and an electronic control unit for activating the components. It is known for a hydraulic connection for a pressure sensor to be provided on a housing block and for the signal of the pressure sensor to be taken into consideration for brake pressure regulation in the control unit. The invention proposes an advantageous arrangement of at least one second hydraulic connection for a second pressure sensor on the housing block in combination with blind bores of the hydraulic connections. The blind bores can be positioned in a variable fashion and formed with different lengths during the production of the housing block. In this way, it is possible for the pressure in different hydraulic partial regions of a vehicle brake system to be sensed in an application-specific manner.
