Abstract
A slip-controlled brake system for automotive vehicles contains a braking pressure modulator (5) operated as a function of the deceleration and having an inert mass (10) which rotates with the vehicle wheel and which, upon a deceleration of the wheel, against resetting forces, is axially displaceable on a shaft (9) rotating with the wheel velocity. A wheel deceleration threshold value being exceeded, a valve member (21) will be actuated and thus the braking pressure will be prevented from increasing further or there even will be a reduction of the braking pressure. The deceleration threshold value is not constant but variable dependence on the braking pressure in the wheel brake (4) of the controlled vehicle wheel. Thereby an adaption of control to the road conditions or rather to the momentary friction coefficient is achieved.
