An electronically controlled pneumatic operating brake system, having a backup control pressure for a pneumatic fall back level, wherein the backup control pressure is generated from a compressed air supply which is independent from two compressed air supplies for a front axle circuit and a rear axle circuit. This assures additional pneumatic redundancy and facilitates omitting a pneumatic channel in a foot brake module.
