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. | |
