<p>A brake system for motor vehicles having a brake master cylinder that can be operated by a brake pedal, a fluid reservoir assigned to the brake master cylinder, a hydraulic booster stage which is operatively connected to the inlet side of the brake master cylinder, with a booster piston which is subjected to a hydraulic boost pressure supplied by a pressure source and which in all operating modes allows a direct mechanical action by the brake pedal on a hydraulic piston of the brake master cylinder, and having an electrically controllable pressure regulating valve arrangement for metering the boost pressure. In order to provide a brake system of simple design, which is cost-effective to produce and which functions reliably, the pressure regulating valve arrangement can be hydraulically controllable.</p> |
