A braking system for automatic driver-independent deceleration of a vehicle includes a hydraulic vehicle brake and a backup braking system. The hydraulic vehicle brake includes an adjustable brake pressure control device. A method for automatic driver-independent deceleration of a vehicle includes decelerating the vehicle by actuating a braking pressure control device and, in response to a set point valve set in a hydraulic vehicle brake exceeding a threshold value, actuating a backup braking system.

A braking method is used for a vehicle that has at least one front wheel and at least one rear wheel. A hydraulically actuatable brake is provided at the front wheel and the rear wheel, and an automatic parking brake is provided at the rear wheel. The braking method enables an optimal brake pressure to be built up as rapidly as possible. In a first step of an initiation phase of the braking method, the front wheel is braked by the hydraulically actuatable brakes and the rear wheel is braked exclusively by the automatic parking brake.
