AbstractA device to provide the control pressure required in the wheel brake cylinder of automotive vehicles incorporating brake slip control apparatus. While it is known to make available the control pressure by a pump-accumulator system, the present invention provides a replaceable pressure reservoir with a highly expansive medium. The fluid reservoir has an exhaustible volume of pressure fluid and a release device actuatable by slip control electronics so that the control pressure is generated only at the beginning of each controlled braking action. This arrangement has a considerable advantage related to manufacturing costs compared to the known arrangements, since there is not need for the pump-accumulator system.
