ABSTRACT:
An automotive brake system comprises a sump fluidly disposed in a housing, constructing a brake unit, and in the middle of a suction circuit of a pressure apply device including at least a pressure apply pump. During vehicle dynamics control or during vehicle stability control, the pressure apply rapidly sucks the brake fluid stored in the sump and quickly performs a pressure apply action, irrespective of the distance between the brake unit and a brake-fluid source. This ensures a smooth brake-fluid supply to the suction circuit of a return pump returning the brake fluid from the wheel-brake cylinder to the brake circuit upstream of a fluid-pressure control valve unit.
