Abstract: A method for checking the availability of a hydraulic fallback level in a power brake system with electronic slip control, an electronic control device, and a power brake system with electronic slip control. In normal operation, power brake systems perform braking procedures without a driver participating in building up braking pressure. A requirement for braking is detected by an electronic control device and associated with a braking pressure which is set by electrical control of the drive of a primary pressure generator. Power brake systems are often equipped with a secondary pressure generator, connected with the wheel brakes, in parallel with the primary pressure generator, which can be used to perform the building up of pressure at a hydraulic fallback level. For safety reasons, the availability of the hydraulic fallback level is checked at particular time intervals during normal braking operation of the power brake system.
