Abstract
To infinitely variably adjust the distance between a reaction disc and an interacting second part of a bipartite valve piston in a completely assembled vacuum brake power booster, which is already mounted to the automotive vehicle, a tubular sleeve is provided, arranged coaxially to a piston rod that actuates the valve piston, and is in engagement with a first part of the valve piston, connected with the second part by a threaded union, to apply a torque to the first piston part. For this purpose, the sleeve has at its end projecting from the control housing with an extension permitting rotation of the sleeve.
