In a deceleration-sensitive braking pressure control device for a vehicular hydraulic brake system, the smaller active surface of a spring-loaded stepped piston faces an inlet chamber communicating with a brake pressure generator and the larger active surface of the stepped piston faces an outlet chamber which communicates with at least one wheel brake cylinder. The two chambers communicate with each other via a channel disposed coaxially in the stepped piston and a valve, the valve including a closure member movable in a deceleration-sensitive manner disposed in the inlet chamber and a valve seat at the adjacent end of the stepped piston. In the rest position of the stepped piston, a stop for the closure member guarantees a minimum distance between the closure member and the valve seat. This stop is provided at the adjacent end of an axially movable sleeve surrounding the adjacent end of the stepped piston.
