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.

Abstract: A hydraulic brake system is provided which does not need a mechanism to feed back the wheel cylinder pressure. The hydraulic brake system generates a brake force by supplying the brake fluid to a wheel cylinder under a high pressure generated by a high pressure source. The brake fluid is supplied to the high pressure source from a reservoir tank storing the brake fluid under atmospheric pressure. A fluid passage connects the high pressure source to both the wheel cylinder and the reservoir tank. An amount of the brake fluid flowing from the high pressure source to the wheel cylinder is controlled by a constant flow valve.
