Front axle braking in the event of degradation

A hydraulic motor vehicle braking system comprising:

• wheel brakes at a front axle of the vehicle;
• wheel brakes at a rear axle of the vehicle;
• an electrical pressure supply device to build-up pressure at the wheel brakes;
• and
• a control device with instructions for:
• implementing a common pressure build-up at the wheel brakes of the front axle and rear axle with the electrical pressure supply device based on a brake demand variable via open inlet valves of the wheel brakes on the front axle and rear axle in the case of no fault;
• closing the inlet valves of the wheel brakes of the rear axle before or at the start of volume delivery via the pressure supply device so that pressure build-up is first implemented via open inlet valves only at the wheel brakes of the front axle in the event of a fault with a degradation of the pressure supply device;
• and
• opening the inlet valves at the wheel brakes on the rear axle when a condition is present.
