A brake system for a vehicle has a first and a second brake control device, four wheel actuator devices, and a first and a second signal line, the first signal line connecting the first brake control device to two of the four wheel actuator devices and the second signal line connecting the second brake control device to the two other wheel actuator devices, each of the four wheel actuator devices in the active state being additionally designed to detect whether a specified number of brake control devices and/or wheel actuator devices are in the inactive state, in which case a specified braking torque is exerted on the wheel of the vehicle associated with the brake control device.
