What can you say about the redundancy valve? In the event of an EBS fault, the redundancy valve ensures that the brake pressure on the rear axle is half the brake pressure on the front axle. The redundancy valve stops the air from the foot brake valve when the EBS is fault-free. The difference in surface area between the top and bottom of the working piston makes a pressure difference possible.
