A method for adjusting brake pressures on pneumatically operated wheel brakes of a motor vehicle includes adjusting, in a normal braking mode, the brake pressures depending on a driver brake request; and adjusting, by a control unit in a pressure control mode, the brake pressures at the respective wheel brakes during reception of an external brake request, which is independent of the driver brake request and defined for the control unit as an external target deceleration value, as a function of a resulting target deceleration value of the vehicle deceleration. The control unit determines the resulting target deceleration value by linking the external target deceleration value according to the external brake request and a value corresponding to the driver brake request. A braking power index is determined which quantitatively represents the braking effect of the wheel brakes, and is provided to be taken into account in pressure control mode.
